122-447: The Mining Journal is a magazine that covers global mining investment, finance, and business. The Mining Journal was founded in 1835 in London by Henry English, a London stockbroker under the name of Mining Journal and Commercial Gazette . In 1860, it was renamed to The Mining Journal, Railway and Commercial Gazette . Its name was changed to The Mining Journal in 1910. In

244-500: A computer to settle the returns for each bet once the details of the wager have been 'translated' into the system by an employee. The added efficiency of this digital system has ensured that there are now very few, if indeed any, betting offices continuing to use microfilm cameras in the UK. Visa and National City use microfilm (roll microfilm and fiche) to store financial, personal, and legal records. Source code for computer programs

366-595: A drawing that is 2.00 × 2.80 metres, that is 79 × 110 in. These films are stored as microfiche. 16 mm or 35 mm film to motion picture standard is used, usually unperforated. Roll microfilm is stored on open reels or put into cassettes. The standard lengths for using roll film is 30.48 m (100 ft) for 35 mm rolls, and 100 ft, 130 ft and 215 feet for 16 mm rolls. One roll of 35 mm film may carry 600 images of large engineering drawings or 800 images of broadsheet newspaper pages. 16 mm film may carry 2,400 images of letter-sized images as

488-399: A format no longer produced, were similar to microfiche, but printed on cardboard rather than photographic film. Equipment is available that accepts a data stream from a computer; this exposes film to produce images as if the stream had been sent to a line printer and the listing had been microfilmed. The process is known as computer output microfilm or computer output microfiche (COM). Using

610-542: A larger area, similar in size to Greater London, although some outer districts are excluded and some just outside included. The Greater London boundary has been aligned to the M25 motorway in places. Further urban expansion is now prevented by the Metropolitan Green Belt , although the built-up area extends beyond the boundary in places, producing a separately defined Greater London Urban Area . Beyond this

732-483: A light source; this is the negative of text on paper. COM is sometimes processed normally. Other applications require that image appears as a conventional negative; the film is then reversal processed. This outputs either 16 mm film or fiche pages on a 105 mm roll. Because listing characters are a simple design, a reduction ratio of 50 gives good quality and puts about 300 pages on a microfiche. A microfilm plotter, sometimes called an aperture card plotter, accepts

854-714: A major part in the establishment of both the Royal School of Mines and the Camborne School of Mines . The British Geological Survey also dates back 180 years, with the formation of the Ordnance Geological Survey in 1835. As indicated, The Mining Journal campaigned vigorously for greater safety in mines and for the establishment of mining schools – the Royal School of Mines opened in 1851 and Camborne School of Mines early in 1888. It

976-584: A matrix of microimages. All microfiche are read with their text parallel to the long side of the fiche . Frames may be landscape or portrait in orientation . Along the top of the fiche a title may be recorded for visual identification. The most commonly used format is a portrait image of about 10 × 14 mm. Office-size papers or magazine pages require a reduction of 24 or 25 in size. Microfiche are stored in open-top envelopes, which are put in drawers or boxes as file cards or fitted into pockets in purpose-made books. Ultrafiche (also "ultramicrofiche" )

1098-452: A means of keeping compact records of bets taken. Betting shop customers would sometimes attempt to amend their betting slip receipt to attempt fraud, and so the microphotography camera (which also generally contained its own independent time-piece) found use as a definitive means of recording the exact details of each and every bet taken. The use of microphotography has now largely been replaced by digital 'bet capture' systems, which also allow

1220-561: A method to microformat dissertations, and in 1934 the United States National Agriculture Library implemented the first microform print-on-demand service, which was quickly followed by a similar commercial concern, Science Service. In 1935, Kodak's Recordak division began filming and publishing The New York Times on reels of 35 millimeter microfilm, ushering in the era of newspaper preservation on film. This method of information storage received

1342-637: A novelty was an opinion shared in the 1858 Dictionary of Photography , which called the process "somewhat trifling and childish". Microphotography was first suggested as a document preservation method in 1851 by the astronomer James Glaisher , and in 1853 by John Herschel , another astronomer. Both men attended the 1851 Great Exhibition in London, where the exhibit on photography greatly influenced Glaisher. He called it "the most remarkable discovery of modern times", and argued in his official report for using microphotography to preserve documents. A pigeon post

1464-403: A population density of 802 per acre (325 per hectare). In addition to the growing number of stores selling goods, such as Harding, Howell & Co. —one of the first department stores —located on Pall Mall , the streets had scores of street sellers . London's overcrowded conditions led to cholera epidemics, claiming 14,000 lives in 1848, and 6,000 in 1866. Rising traffic congestion led to

1586-573: A population of 7,172,036 in 2001 and a population density of 11,760 inhabitants per square mile (4,542/km ). The extended area known as the London Metropolitan Region or the London Metropolitan Agglomeration, comprises a total area of 3,236 square miles (8,382 km ) has a population of 13,709,000 and a population density of 3,900 inhabitants per square mile (1,510/km ). Modern London stands on

1708-401: A reduced size. The prints were on photographic paper and did not exceed 40 mm, to permit insertion in a goose-quill or thin metal tube, which protected against the elements. The pigeons each carried a dispatch that was tightly rolled and tied with a thread, and then attached to a tail feather of the pigeon. The dispatch was protected by being inserted in the quill, which was then attached to

1830-412: A simple, inexpensive ($ 2.00 in 1950), monocular microfilm viewing device, known as the "Seidell viewer", that was sold during the 1940s and 1950s. A microfilm printer contains a xerographic copying process, like a photocopier . The image to be printed is projected with synchronised movement on to the drum. These devices offer either small image preview for the operator or full size image preview, when it

1952-414: A single film may be inserted into a dark slide or the camera may be fitted with a roll film holder which after an exposure advances the film into a box and cuts the frame off the roll for processing as a single film. For engineering drawings, a freestanding open steel structure is often provided. A camera may be moved vertically on a track. Drawings are placed on a large table for filming, with centres under

2074-406: A single stream of microimages along the film set so that lines of text are parallel to the sides of the film or 10,000 small documents, perhaps cheques or betting slips, with both sides of the originals set side by side on the film. Aperture cards are Hollerith cards into which a hole has been cut. A 35 mm microfilm chip is mounted in the hole inside of a clear plastic sleeve or secured over

2196-401: A square inch, and that a one-foot cube could contain 1.5 million volumes. In 1906, Paul Otlet and Robert Goldschmidt proposed the livre microphotographique as a way to alleviate the cost and space limitations imposed by the codex format. Otlet's overarching goal was to create a World Center Library of Juridical, Social and Cultural Documentation, and he saw microfiche as a way to offer

2318-554: A stable and durable format that was inexpensive, easy to use, easy to reproduce, and extremely compact. In 1925, the team spoke of a massive library where each volume existed as master negatives and positives, and where items were printed on demand for interested patrons. In the 1920s, microfilm began to be used in a commercial setting. New York City banker George McCarthy was issued a patent in 1925 for his "Checkograph" machine, designed to make micrographic copies of cancelled checks for permanent storage by financial institutions. In 1928,

2440-470: A step and repeat mechanism to advance the film after each exposure. The simpler versions use a dark slide loaded by the operator in a dark room; after exposure the film is individually processed, which may be by hand or using a dental X-ray processor. Cameras for high output are loaded with a roll of 105 mm film. The exposed film is developed as a roll; this is sometimes cut to individual fiche after processing or kept in roll form for duplication. Equipment

2562-689: A storage medium than earlier methods of film information storage, such as the Photoscope, the Film-O-Graph, the Fiske-O-Scope, and filmslides. The year 1938 also saw another major event in the history of microfilm when University Microfilms International (UMI) was established by Eugene Power . For the next half century, UMI would dominate the field, filming and distributing microfilm editions of current and past publications and academic dissertations. After another short-lived name change, UMI

2684-411: A stream that might be sent to a computer pen plotter. It produces corresponding frames of microfilm. These produce microfilm as 35 or 16 mm film or aperture cards. Computer Output Microfiche was used to distribute massive amounts of frequently changed data to institutions or companies which could not afford computer terminals but already used microfiche readers for a variety of reasons. In some cases

2806-551: A temperate oceanic climate ( Köppen : Cfb ). Rainfall records have been kept in the city since at least 1697, when records began at Kew . At Kew, the most rainfall in one month is 7.4 inches (189 mm) in November 1755 and the least is 0 inches (0 mm) in both December 1788 and July 1800. Mile End also had 0 inches (0 mm) in April 1893. The wettest year on record is 1903, with a total fall of 38.1 inches (969 mm) and

2928-699: Is 1,049.8 millibars (31.00 inHg) on 20 January 2020. Summers are generally warm, sometimes hot. London's average July high is 23.5 °C (74.3 °F). On average each year, London experiences 31 days above 25 °C (77.0 °F) and 4.2 days above 30.0 °C (86.0 °F). During the 2003 European heat wave , prolonged heat led to hundreds of heat-related deaths. A previous spell of 15 consecutive days above 32.2 °C (90.0 °F) in England in 1976 also caused many heat related deaths. A previous temperature of 37.8 °C (100.0 °F) in August 1911 at

3050-482: Is an exceptionally compact version of a microfiche or microfilm, storing analog data at much higher densities. Ultrafiche can be created directly from computers using appropriate peripherals. They are typically used for storing data gathered from extremely data-intensive operations such as remote sensing. Microcards are an opaque, non-reversed format, sometimes known as microopaques. They were invented in 1948 by Fremont Rider and described in his book, The Scholar and

3172-402: Is available that accepts a data stream from a mainframe computer. This exposes film to produce images as if the stream had been sent to a line printer and the listing had been microfilmed. Because of the source one run may represent many thousands of pages. The process is known as computer output microfilm or computer output microfiche (COM). Within the equipment character images are made by

3294-581: Is built into a box. In some versions this is for bench top use, other versions are portable. The operator maintains a stack of material to be filmed in a tray, the camera automatically takes one document after another for advancement through the machine. The camera lens sees the documents as they pass a slot. Film behind the lens advances exactly with the image. Special purpose flow cameras film both sides of documents, putting both images side by side on 16 mm film. These cameras are used to record cheques and betting slips. All microfiche cameras are planetary with

3416-411: Is called a reader printer. Microform printers can accept positive or negative films and positive or negative images on paper. New machines allow the user to scan a microform image and save it as a digital file. 105 × 148 mm flat film is used for microimages of very large engineering drawings. These may carry a title photographed or written along one edge. Typical reduction is about 20, representing

3538-545: Is formed of two tiers: a citywide, strategic tier and a local tier. Citywide administration is coordinated by the Greater London Authority (GLA), while local administration is carried out by 33 smaller authorities. The GLA consists of two elected components: the mayor of London , who has executive powers , and the London Assembly , which scrutinises the mayor's decisions and can accept or reject

3660-707: Is headquartered in Thames House on the north bank of the River Thames and the foreign intelligence service ( MI6 ) is headquartered in the SIS Building on the south bank. Crime rates vary widely across different areas of London. Crime figures are made available nationally at Local Authority and Ward level. In 2015, there were 118 homicides, a 25.5% increase over 2014. Recorded crime has been rising in London, notably violent crime and murder by stabbing and other means have risen. There were 50 murders from

3782-642: Is held by an independent . The ministerial post of minister for London was created in 1994, however as of 2024, the post has been vacant. Policing in Greater London, with the exception of the City of London , is provided by the Metropolitan Police ("The Met"), overseen by the mayor through the Mayor's Office for Policing and Crime (MOPAC). The Met is also referred to as Scotland Yard after

3904-423: Is in use. They may offer a choice of magnifications. They usually have motors to advance and rewind film. When coding blips are recorded on the film a reader is used that can read the blips to find any required image. Portable readers are plastic devices that fold for carrying; when open they project an image from microfiche on to a reflective screen. For example, with M. de Saint Rat , Atherton Seidell developed

4026-564: Is known as London . It is the capital of the United Kingdom and of England by convention rather than statute. The capital of England was moved to London from Winchester as the Palace of Westminster developed in the 12th and 13th centuries to become the permanent location of the royal court , and thus the political capital of the nation. Greater London encompasses a total area of 611 square miles (1,583 km ) an area which had

4148-501: Is provided 16, 35 and 105 mm wide in lengths of 30 metres (100 ft) and longer, and is usually unperforated. Roll film is developed, fixed and washed by continuous processors. Sheet film is supplied in ISO A6 size. This is either processed by hand or using a dental X-ray processor. Camera film is supplied ready mounted in aperture cards. Aperture cards are developed, fixed and washed immediately after exposure by equipment fitted to

4270-610: Is the fourth-most populous in Europe, with about 9.8 million inhabitants as of 2011. The London metropolitan area is the third-most populous in Europe, with about 14 million inhabitants as of 2016, making London a megacity . Four World Heritage Sites are located in London: Kew Gardens ; the Tower of London ; the site featuring the Palace of Westminster , Church of St. Margaret , and Westminster Abbey ; and

4392-523: Is the vast London commuter belt . Greater London is split for some purposes into Inner London and Outer London , and by the River Thames into North and South , with an informal central London area. The coordinates of the nominal centre of London, traditionally the original Eleanor Cross at Charing Cross near the junction of Trafalgar Square and Whitehall , are about 51°30′26″N 00°07′39″W  /  51.50722°N 0.12750°W  / 51.50722; -0.12750 . Within London, both

London was a centre of England's Jewish population before their expulsion by Edward I in 1290. Violence against Jews occurred in 1190, when it was rumoured that the new king had ordered their massacre after they had presented themselves at his coronation. In 1264 during

4636-589: The Canary Wharf development. This was born out of London's increasing role as an international financial centre in the 1980s. Located about 2 miles (3 km) east of central London, the Thames Barrier was completed in the 1980s to protect London against tidal surges from the North Sea . The Greater London Council was abolished in 1986, leaving London with no central administration until 2000 and

4758-575: The City of London , but since then it has also referred to the County of London and to Greater London . In 1993, remains of a Bronze Age bridge were found on the south River Thames foreshore, upstream from Vauxhall Bridge . Two of the timbers were radiocarbon dated to 1750–1285 BC. In 2010, foundations of a large timber structure, dated to 4800–4500 BC, were found on the Thames' south foreshore downstream from Vauxhall Bridge. Both structures are on

4880-672: The Corn Laws in 1846 was specifically aimed at weakening Dutch economic power. London then overtook Amsterdam as the leading international financial centre. With the onset of the Industrial Revolution in Britain, an unprecedented growth in urbanisation took place, and the number of High Streets (the primary street for retail in Britain) rapidly grew. London was the world's largest city from about 1831 to 1925 , with

5002-980: The Eastman Kodak Company bought McCarthy's invention and began marketing check microfilming devices under its "Recordak" division. Between 1927 and 1935, the Library of Congress microfilmed more than three million pages of books and manuscripts in the British Library ; in 1929 the Social Science Research Council and the American Council of Learned Societies joined to create a Joint Committee on Materials for Research, chaired for most of its existence by Robert C. Binkley , which looked closely at microform's potential to serve small print runs of academic or technical materials. In 1933, Charles C. Peters developed

5124-809: The FA Cup Final , the Wimbledon Tennis Championships , and the London Marathon . It became the first city to host three Summer Olympic Games upon hosting the 2012 Summer Olympics . London is an ancient name, attested in the first century AD, usually in the Latinised form Londinium . Modern scientific analyses of the name must account for the origins of the different forms found in early sources: Latin (usually Londinium ), Old English (usually Lunden ), and Welsh (usually Llundein ), with reference to

5246-568: The Georgian era , new districts such as Mayfair were formed in the west; new bridges over the Thames encouraged development in South London . In the east, the Port of London expanded downstream. London's development as an international financial centre matured for much of the 18th century. In 1762, George III acquired Buckingham House , which was enlarged over the next 75 years. During

5368-497: The Greater London Authority . As one of the world's major global cities , London exerts a strong influence on world art , entertainment, fashion , commerce, finance, education , healthcare , media , science, technology, tourism , transport , and communications. Despite a post- Brexit exodus of stock listings from the London Stock Exchange , London remains a European economic powerhouse, and one of

5490-634: The King's Road , Chelsea and Carnaby Street . The role of trendsetter revived in the punk era. In 1965 London's political boundaries were expanded in response to the growth of the urban area and a new Greater London Council was created. During The Troubles in Northern Ireland, London was hit from 1973 by bomb attacks by the Provisional Irish Republican Army . These attacks lasted for two decades, starting with

5612-687: The London Ambulance Service (LAS) NHS Trust , the largest free-at-the-point-of-use emergency ambulance service in the world. The London Air Ambulance charity operates in conjunction with the LAS where required. Her Majesty's Coastguard and the Royal National Lifeboat Institution operate on the River Thames , which is under the jurisdiction of the Port of London Authority from Teddington Lock to

5734-782: The Mediterranean was normally through Antwerp and over the Alps ; any ships passing through the Strait of Gibraltar to or from England were likely to be Italian or Ragusan . The reopening of the Netherlands to English shipping in January 1565 spurred a burst of commercial activity. The Royal Exchange was founded. Mercantilism grew and monopoly traders such as the East India Company were founded as trade expanded to

5856-613: The New Model Army entered London in 1647, and they were levelled by Parliament the same year. London was plagued by disease in the early 17th century, culminating in the Great Plague of 1665–1666, which killed up to 100,000 people, or a fifth of the population. The Great Fire of London broke out in 1666 in Pudding Lane in the city and quickly swept through the wooden buildings. Rebuilding took over ten years and

5978-564: The New World . London became the main North Sea port, with migrants arriving from England and abroad. The population rose from about 50,000 in 1530 to about 225,000 in 1605. In the 16th century, William Shakespeare and his contemporaries lived in London during English Renaissance theatre . Shakespeare's Globe Theatre was constructed in 1599 in Southwark . Stage performances came to a halt in London when Puritan authorities shut down

6100-612: The Old Bailey bombing . Racial inequality was highlighted by the 1981 Brixton riot . Greater London's population declined in the decades after the Second World War, from an estimated peak of 8.6 million in 1939 to around 6.8 million in the 1980s. The principal ports for London moved downstream to Felixstowe and Tilbury , with the London Docklands area becoming a focus for regeneration, including

6222-662: The Second Barons' War , Simon de Montfort 's rebels killed 500 Jews while attempting to seize records of debts. During the Tudor period , the Reformation produced a gradual shift to Protestantism . Much of London property passed from church to private ownership, which accelerated trade and business in the city. In 1475, the Hanseatic League set up a main trading base ( kontor ) of England in London, called

6344-585: The Stalhof or Steelyard . It remained until 1853, when the Hanseatic cities of Lübeck , Bremen and Hamburg sold the property to South Eastern Railway . Woollen cloth was shipped undyed and undressed from 14th/15th century London to the nearby shores of the Low Countries . Yet English maritime enterprise hardly reached beyond the seas of north-west Europe . The commercial route to Italy and

6466-547: The Thames , its primary geographical feature, a navigable river which crosses the city from the south-west to the east. The Thames Valley is a flood plain surrounded by gently rolling hills including Parliament Hill , Addington Hills , and Primrose Hill . Historically London grew up at the lowest bridging point on the Thames. The Thames was once a much broader, shallower river with extensive marshlands ; at high tide, its shores reached five times their present width. Since

6588-533: The Victorian era the Thames has been extensively embanked , and many of its London tributaries now flow underground . The Thames is a tidal river, and London is vulnerable to flooding. The threat has increased over time because of a slow but continuous rise in high water level caused by climate change and by the slow 'tilting' of the British Isles as a result of post-glacial rebound . London has

6710-494: The daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs , in 1839. He achieved a reduction ratio of 160:1. Dancer refined his reduction procedures with Frederick Scott Archer 's wet collodion process , developed in 1850–51, but he dismissed his decades-long work on microphotographs as a personal hobby and did not document his procedures. The idea that microphotography could be no more than

6832-516: The 11th century, London was clearly the largest town in England. Westminster Abbey , rebuilt in Romanesque style by King Edward the Confessor , was one of the grandest churches in Europe. Winchester had been the capital of Anglo-Saxon England , but from this time London became the main forum for foreign traders and the base for defence in time of war. In the view of Frank Stenton : "It had

6954-430: The 1830s, and it is clear from the early issues that the founders – led by the first editor, Henry English – realized they were witnessing an evolution in mining. Michael Coulson, author of The History of Mining , wrote that English believed with the Industrial Revolution in full swing and the mining industry providing the key raw materials driving industrialization , “a regular publication recording and commenting on

7076-502: The 18th century, London was said to be dogged by crime, and the Bow Street Runners were established in 1750 as a professional police force. Epidemics during the 1720s and 30s saw most children born in the city die before reaching their fifth birthday. Coffee-houses became a popular place to debate ideas, as growing literacy and development of the printing press made news widely available, with Fleet Street becoming

7198-452: The 19th century , becoming the world's largest city at the time . Since the 19th century, the name "London" has referred to the metropolis around the City of London, historically split between the counties of Middlesex , Essex , Surrey , Kent , and Hertfordshire , which since 1965 has largely comprised the administrative area of Greater London , governed by 33 local authorities and

7320-420: The City of London and the City of Westminster have city status . The City of London and the remainder of Greater London are both counties for the purposes of lieutenancies . The area of Greater London includes areas that are part of the historic counties of Middlesex , Kent , Surrey , Essex and Hertfordshire . More recently, Greater London has been defined as a region of England and in this context

7442-688: The Environment , GeoDrilling International and World Tunnelling/Trenchless World . Since 2008, it has been owned by the Australian company Aspermont. Issues of the Mining Journal from No.1 (29th August 1835) to No.3201 (26th December 1896) were digitised from microfische and published on Archive.org in 2021. In addition to the complete series of weekley issues; volume indicies from 1951 ( vol.236 ) to 1999 ( vol.332 ) were also published. An online index of mining companies mentioned in

7564-701: The Future of the Research Library . To create microform media, a planetary camera is mounted with the vertical axis above a copy that is stationary during exposure. High volume output is possible with a rotary camera which moves the copy smoothly through the camera to expose film which moves with the reduced image. Alternatively, it may be produced by computers, i.e. COM (computer output microfilm). Normally microfilming uses high resolution panchromatic monochrome stock. Positive color film giving good reproduction and high resolution can also be used. Roll film

Droughts can also, occasionally, be a problem, especially in summer, most recently in summer 2018, and with much drier than average conditions prevailing from May to December. However, the most consecutive days without rain was 73 days in the spring of 1893. Microform Three formats are common: microfilm (reels), microfiche (flat sheets), and aperture cards . Microcards, also known as "micro-opaques",

7808-435: The London area. This called for the Corporation of the city to extend its jurisdiction and administration over expanding areas around the city. Fearing an attempt by the Crown to diminish the Liberties of London , coupled with a lack of interest in administering these additional areas or concern by city guilds of having to share power, caused the Corporation's "The Great Refusal", a decision which largely continues to account for

7930-418: The Mining Journal compiled by Alastair Neil is published by the Northern Mines Research Society . London London is the capital and largest city of both England and the United Kingdom , with a population of 8,866,180 in 2022. The wider metropolitan area is the largest in Western Europe , with a population of 14.9 million. London stands on the River Thames in southeast England, at

8052-490: The US, while he was a mining engineer then working in London. In 1935, as a centenary edition, it launched Mining Annual Review and in the 1990s expanded through the launch of World Tunnelling , Geodrilling International , Mining Environmental Management (now Mining People and the Environment ). " In 1844, The Mining Journal successfully campaigned for the introduction of the first safety regulations for mines. A large number of important inventions were introduced in

8174-405: The Viking incursions formally agreed by the Danish warlord , Guthrum and the West Saxon king Alfred the Great in 886. The Anglo-Saxon Chronicle records that Alfred "refounded" London in 886. Archaeological research shows this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls . London then grew slowly until a dramatic increase in about 950. By

Aperture cards may be stored in drawers or in freestanding rotary units. A microfiche is a sheet of flat film, 105 × 148 mm in size, the same size as the international standard for paper size ISO A6 . It carries

8418-608: The camera. Early cut sheet microforms and microfilms (to the 1930s) were printed on nitrate film , which poses high risks to their holding institutions, as nitrate film is chemically unstable and a fire hazard. From the late 1930s to the 1980s, microfilms were usually printed on a cellulose acetate base, which is prone to tears, vinegar syndrome , and redox blemishes. Vinegar syndrome is the result of chemical decay and produces "buckling and shrinking, embrittlement, and bubbling". Redox blemishes are yellow, orange or red spots 15–150 micrometres in diameter created by oxidative attacks on

8540-499: The card. This permits automated reproduction, as well as permitting mechanical card-sorting equipment to sort and select microfilm drawings. Aperture card mounted microfilm is roughly 3% of the size and space of conventional paper or vellum engineering drawings. Some military contracts around 1980 began to specify digital storage of engineering and maintenance data because the expenses were even lower than microfilm, but these programs are now finding it difficult to purchase new readers for

8662-437: The centre of the British press. The invasion of Amsterdam by Napoleonic armies led many financiers to relocate to London and the first London international issue was arranged in 1817. Around the same time, the Royal Navy became the world's leading war fleet, acting as a major deterrent to potential economic adversaries. Following a fire in 1838, the Royal Exchange was redesigned by William Tite and rebuilt in 1844. The repeal of

8784-484: The city's metropolis. The City of London at its core once comprised the whole settlement, but as its urban area grew, the Corporation of London resisted attempts to amalgamate the city with its suburbs , causing "London" to be defined several ways. Forty per cent of Greater London is covered by the London post town , in which 'London' forms part of postal addresses. The London telephone area code (020) covers

8906-412: The city, to intimidate the inhabitants. In 1097, William II began building Westminster Hall , near the abbey. It became the basis of a new Palace of Westminster . In the 12th century, the institutions of central government, which had hitherto followed the royal English court around the country, grew in size and sophistication and became increasingly fixed, for most purposes at Westminster , although

9028-600: The combined revenue expenditure by London councils and the GLA amounted to just over £22 billion (£14.7 billion for the boroughs and £7.4 billion for the GLA). The London Fire Brigade is the statutory fire and rescue service for Greater London, run by the London Fire and Emergency Planning Authority . It is the third largest fire service in the world. National Health Service ambulance services are provided by

9150-626: The creation of the Greater London Authority . To mark the 21st century, the Millennium Dome , London Eye and Millennium Bridge were constructed. On 6 July 2005 London was awarded the 2012 Summer Olympics , as the first city to stage the Olympic Games three times. On 7 July 2005, three London Underground trains and a double-decker bus were bombed in a series of terrorist attacks . In 2008, Time named London alongside New York City and Hong Kong as Nylonkong , hailing them as

9272-559: The creation of the London Underground , the world's first urban rail network . The Metropolitan Board of Works oversaw infrastructure expansion in the capital and some surrounding counties; it was abolished in 1889 when the London County Council was created out of county areas surrounding the capital. From the early years of the 20th century onwards, teashops were found on High Streets across London and

9394-580: The dispatches onto paper. Additionally, the US Victory Mail , and the British "Airgraph" system it was based on, were used for delivering mail between those at home and troops serving overseas during World War II . The systems worked by photographing large amounts of censored mail reduced to thumb-nail size onto reels of microfilm, which weighed much less than the originals would have. The film reels were shipped by priority air freight to and from

9516-713: The driest is 1921, with a total fall of 12.1 inches (308 mm). The average annual precipitation amounts to about 600mm, which is half the annual rainfall of New York City . Despite relatively low annual precipitation, London receives 109.6 rainy days on the 1.0mm threshold annually. London is vulnerable to climate change , and there is concern among hydrological experts that households may run out of water before 2050. Temperature extremes in London range from 40.2 °C (104.4 °F) at Heathrow on 19 July 2022 down to −17.4 °C (0.7 °F) at Northolt on 13 December 1981. Records for atmospheric pressure have been kept at London since 1692. The highest pressure ever reported

9638-515: The early days of The Mining Journal , then known as The Mining Journal and Commercial Gazette , it carried information on a range of subjects, from mines , machinery and metals prices, to news items and stories of general interest. The early issues also provided a glossary of mining terms, updated regularly, and noted all known mine accidents. In 1963, The Mining Journal Ltd took over rival publication Mining Magazine , which had been founded in 1909 by Herbert Hoover , later to become President of

9760-538: The fast growing industry. English became something of a one-man protest movement and his commentaries became increasingly influential, culminating in his success in having a commission appointed to look into the Haswell Colliery disaster in Durham in 1844 following his direct appeal to Queen Victoria . The Mining Journal continued to campaign for reform of the mining industry and English's efforts played

9882-409: The film, and are largely due to poor storage conditions. The simplest microfilm camera that is still in use is a rail mounted structure at the top of which is a bellows camera for 105 x 148 mm film. A frame or copy board holds the original drawing vertical. The camera has a horizontal axis which passes through the center of the copy. The structure may be moved horizontally on rails. In a darkroom

10004-609: The first Muslim mayor of a major Western capital. The mayor's statutory planning strategy is published as the London Plan , which was most recently revised in 2011. The local authorities are the councils of the 32 London boroughs and the City of London Corporation . They are responsible for most local services, such as local planning, schools, libraries, leisure and recreation, social services , local roads and refuse collection. Certain functions, such as waste management , are provided through joint arrangements. In 2009–2010

10126-494: The head of a 50-mile (80 km) estuary down to the North Sea , and has been a major settlement for nearly 2,000 years. Its ancient core and financial centre , the City of London , was founded by the Romans as Londinium and has retained its medieval boundaries. The City of Westminster , to the west of the City of London, has been the centuries-long host of the national government and parliament . London grew rapidly in

10248-821: The historic settlement in Greenwich where the Royal Observatory defines the prime meridian (0° longitude ) and Greenwich Mean Time . Other landmarks include Buckingham Palace , the London Eye , Piccadilly Circus , St Paul's Cathedral , Tower Bridge , and Trafalgar Square . The city has the most museums , art galleries, libraries, and cultural venues in the UK, including the British Museum , National Gallery , Natural History Museum , Tate Modern , British Library , and numerous West End theatres. Important sporting events held in London include

10370-431: The home fronts, sent to their prescribed destinations for enlarging at receiving stations near the recipients, and printed out on lightweight photo paper. These facsimiles of the letter-sheets were reproduced about one-quarter the original size and the miniature mails were then delivered to the addressee. Use of these microfilm systems saved significant volumes of cargo capacity needed for war supplies. An additional benefit

10492-401: The issues facing mining was long overdue”. “Exposed to the oxygen of publicity it was clear that all was not well with the UK's mining industry – its size, excepting coal , was inadequate to provide all the needs of rapidly growing industries such as iron , steel and engineering ,” Coulson wrote. At the same time, coal mining in the UK was dangerous and fatalities unacceptably common in

10614-404: The known developments over time of sounds in those different languages. It is agreed that the name came into these languages from Common Brythonic ; recent work tends to reconstruct the lost Celtic form of the name as * Londonjon or something similar. This was then adapted into Latin as Londinium and borrowed into Old English. Until 1889, the name "London" applied officially only to

10736-414: The lens. Fixed lights illuminate the copy. These cameras are often over 4 metres (13 ft) high. These cameras accept roll film stock of 35 or 16 mm. For office documents a similar design may be used but bench standing. This is a smaller version of the camera described above. These are provided either with the choice of 16 or 35 mm film or accepting 16 mm film only. Non adjustable versions of

10858-640: The location of its original headquarters in a road called Great Scotland Yard in Whitehall. The City of London has its own police force – the City of London Police . First worn by Met police officers in 1863, the custodian helmet has been called a "cultural icon" and a "symbol of British law enforcement". Introduced by the Met in 1929, the blue police telephone box (basis for the TARDIS in Doctor Who )

10980-409: The mayor's budget proposals each year. The GLA has responsibility for the majority of London's transport system through its functional arm Transport for London (TfL), it is responsible for overseeing the city's police and fire services, and also for setting a strategic vision for London on a range of issues. The headquarters of the GLA is City Hall , Newham. The mayor since 2016 has been Sadiq Khan ,

11102-499: The microphotograph was reattached to a glass frame and was then projected by magic lantern on the wall. The message contained in the microfilm could then be transcribed or copied. By 28 January 1871, when Paris and the Government of National Defense surrendered, Dagron had delivered 115,000 messages to Paris by carrier pigeon. The chemist Charles-Louis Barreswil proposed the application of photographic methods with prints of

11224-675: The most diverse cities in the world. In 1951, the Festival of Britain was held on the South Bank . The Great Smog of 1952 led to the Clean Air Act 1956 , which ended the " pea soup fogs " for which London had been notorious, and had earned it the nickname the "Big Smoke". Starting mainly in the mid-1960s, London became a centre for worldwide youth culture , exemplified by the Swinging London sub-culture associated with

11346-400: The office camera are provided. These have a rigid frame or an enveloping box that holds a camera at a fixed position over a copy board. If this is to work at more than one reduction ratio there are a choice of lenses. Some cameras expose a pattern of light, referred to as blips, to digitally identify each adjacent frame. This pattern is copied whenever the film is copied for searching. A camera

11468-467: The old Roman city. By about 680 the city had become a major port again, but there is little evidence of large-scale production. From the 820s repeated Viking assaults brought decline. Three are recorded; those in 851 and 886 succeeded, while the last, in 994, was rebuffed. The Vikings applied Danelaw over much of eastern and northern England, its boundary running roughly from London to Chester as an area of political and geographical control imposed by

11590-796: The old formats. Microfilm first saw military use during the Franco-Prussian War of 1870–71. During the Siege of Paris , the only way for the provisional government in Tours to communicate with Paris was by pigeon post . As the pigeons could not carry paper dispatches, the Tours government turned to microfilm. Using a microphotography unit evacuated from Paris before the siege, clerks in Tours photographed paper dispatches and compressed them to microfilm, which were carried by homing pigeons into Paris and projected by magic lantern while clerks copied

11712-490: The principal city of the Roman province of Britannia in 100. At its height in the 2nd century, Roman London had a population of about 60,000. With the early 5th-century collapse of Roman rule, the walled city of Londinium was effectively abandoned, although Roman civilisation continued around St Martin-in-the-Fields until about 450. From about 500, an Anglo-Saxon settlement known as Lundenwic developed slightly west of

11834-421: The quantities involved justified getting a microfiche reader just to read COM fiche. The first COM devices date back to around 1955 and were used in scientific programming as substitutes for paper-based plotters . Then during the 1960s, business applications sought to use COM. This was part of the effort to find alternatives to paper-based reports in dealing with the information explosion . By 1969, some of

11956-466: The resources, and it was rapidly developing the dignity and the political self-consciousness appropriate to a national capital ." After winning the Battle of Hastings , William, Duke of Normandy was crowned King of England in newly completed Westminster Abbey on Christmas Day 1066. William built the Tower of London , the first of many such in England rebuilt in stone in the south-eastern corner of

12078-641: The rest of Britain, with Lyons , who opened the first of their chain of teashops in Piccadilly in 1894, leading the way. The tearooms, such as the Criterion in Piccadilly, became a popular meeting place for women from the suffrage movement. The city was the target of many attacks during the suffragette bombing and arson campaign , between 1912 and 1914, which saw historic landmarks such as Westminster Abbey and St Paul's Cathedral bombed. London

12200-401: The royal treasury came to rest in the Tower . While the City of Westminster developed into a true governmental capital, its distinct neighbour, the City of London , remained England's largest city and principal commercial centre and flourished under its own unique administration, the Corporation of London . In 1100, its population was some 18,000; by 1300 it had grown to nearly 100,000. With

12322-776: The sanction of the American Library Association at its annual meeting in 1936, when it officially endorsed microforms. In 1937 Herman H. Fussler of the University of Chicago set up an exhibition of microform at the World Congress of Universal Documentation . Harvard University Library was the first major institution to realize the potential of microfilm to preserve broadsheets printed on high-acid newsprint and it launched its "Foreign Newspaper Project" to preserve such ephemeral publications in 1938. Roll microfilm proved far more satisfactory as

12444-488: The sea. London is the seat of the Government of the United Kingdom . Many government departments, as well as the prime minister's residence at 10 Downing Street , are based close to the Palace of Westminster , particularly along Whitehall . There are 75 members of Parliament (MPs) from London; As of June 2024 , 59 are from the Labour Party , 9 are Conservatives , 6 are Liberal Democrats and one constituency

12566-541: The south bank of the Thames, where the now-underground River Effra flows into the Thames. Despite the evidence of scattered Brythonic settlements in the area, the first major settlement was founded by the Romans around 47 AD, about four years after their invasion of 43 AD. This only lasted until about 61 AD, when the Iceni tribe led by Queen Boudica stormed it and burnt it to the ground. The next planned incarnation of Londinium prospered, superseding Colchester as

12688-424: The start of 2018 to mid April 2018. Funding cuts to police in London are likely to have contributed to this, though other factors are involved. However, homicide figures fell in 2022 with 109 recorded for the year, and the murder rate in London is much lower than other major cities around the world. London, also known as Greater London , is one of nine regions of England and the top subdivision covering most of

12810-423: The tail feather. The developments in microphotography continued through the next decades, but it was not until the turn of the century that its potential for practical usage was applied more broadly. In 1896, Canadian engineer Reginald A. Fessenden suggested microforms were a compact solution to engineers' unwieldy but frequently consulted materials. He proposed that up to 150,000,000 words could be made to fit in

12932-753: The theatres in the 1640s. The ban on theatre was lifted during the Restoration in 1660, and London's oldest operating theatre, Drury Lane , opened in 1663 in what is now the West End theatre district. By the end of the Tudor period in 1603, London was still compact. There was an assassination attempt on James I in Westminster, in the Gunpowder Plot of 5 November 1605. In 1637, the government of Charles I attempted to reform administration in

13054-715: The unique governmental status of the City . In the English Civil War , the majority of Londoners supported the Parliamentary cause. After an initial advance by the Royalists in 1642, culminating in the battles of Brentford and Turnham Green , London was surrounded by a defensive perimeter wall known as the Lines of Communication . The lines were built by up to 20,000 people, and were completed in under two months. The fortifications failed their only test when

13176-413: The world's busiest city airport system . The London Underground is the world's oldest rapid transit system. London's diverse cultures encompass over 300 languages. The 2023 population of Greater London of just under 10 million made it Europe's third-most populous city , accounting for 13.4% of the United Kingdom's population and over 16% of England's population. The Greater London Built-up Area

13298-468: The world's major financial centres . It hosts Europe's largest concentration of higher education institutions , some of which are the highest-ranked academic institutions in the world: Imperial College London in natural and applied sciences , the London School of Economics in social sciences , and the comprehensive University College London . It is the most visited city in Europe and has

13420-639: The world's three most influential global cities . In January 2015, Greater London's population was estimated to be 8.63 million, its highest since 1939. During the Brexit referendum in 2016, the UK as a whole decided to leave the European Union , but most London constituencies voted for remaining. However, Britain's exit from the EU in early 2020 only marginally weakened London's position as an international financial centre. The administration of London

13542-1023: Was bombed by the Germans in the First World War , and during the Second World War , the Blitz and other bombings by the German Luftwaffe killed over 30,000 Londoners, destroying large tracts of housing and other buildings across the city. The tomb of the Unknown Warrior , an unidentified member of the British armed forces killed during the First World War, was buried in Westminster Abbey on 11 November 1920. The Cenotaph , located in Whitehall ,

13664-459: Was also a space-saving measure. In his 1945 book, The Scholar and the Future of the Research Library , Fremont Rider calculated that research libraries were doubling in space every sixteen years. His suggested solution was microfilming, specifically with his invention, the microcard. Once items were put onto film, they could be removed from circulation and additional shelf space would be made available for rapidly expanding collections. The microcard

13786-411: Was in operation during the Siege of Paris (1870-1871). René Dagron photographed pages of newspapers in their entirety which he then converted into miniature photographs. He subsequently removed the collodion film from the glass base and rolled it tightly into a cylindrical shape which he then inserted into miniature tubes that were transported fastened to the tail feathers of the pigeons. Upon receipt

13908-476: Was latterly passed on to Lawrence Williams, in conjunction with Michael West and Christopher Hinde as minority shareholders, who ran it for the next decade. During that period the company launched World Tunnelling , Geodrilling International , No-Dig International , World Gold and Mining Environmental Management magazines. In 2005, ownership was transferred to the publishing company, Mining Communications, which also produces Mining Magazine , Mining, People and

14030-452: Was made a part of ProQuest Information and Learning in 2001. Systems that mount microfilm images in punched cards have been widely used for archival storage of engineering information. For example, when airlines demand archival engineering drawings to support purchased equipment (in case the vendor goes out of business, for example), they normally specify punch-card-mounted microfilm with an industry-standard indexing system punched into

14152-437: Was once a common sight throughout London and regional cities in the UK. The British Transport Police are responsible for police services on National Rail , London Underground , Docklands Light Railway and Tramlink services. The Ministry of Defence Police is a special police force in London, which does not generally become involved with policing the general public. The UK's domestic counter-intelligence service ( MI5 )

14274-464: Was owned and managed by independent company Mining Journal Limited, owned by the Baliol Scott family for many years, during which it acquired, and continued to publish Mining Magazine , a monthly publication launched by subsequent U.S. President Herbert Hoover when he was a London-based mining engineer, in 1909, until ownership was passed to Michael West, who ran it successfully for two decades. It

14396-413: Was printed to microfiche during the 1970s and distributed to customers in this form. Additionally, microfiche was used to write out long casework for some proofs such as the four color theorem . The medium has numerous characteristics: Desktop readers are boxes with a translucent screen at the front on to which is projected an image from a microform. They have suitable fittings for whatever microform

14518-567: Was superseded by microfiche. By the 1960s, microfilming had become standard policy. In 1948, the Australian Joint Copying Project started; the intention to film records and archives from the United Kingdom relating to Australia and the Pacific. Over 10,000 reels were produced, making it one of the largest projects of its kind. Around the same time, Licensed Betting Offices in the UK began using microphotography as

14640-465: Was supervised by polymath Robert Hooke . In 1710, Christopher Wren 's masterpiece, St Paul's Cathedral , was completed, replacing its medieval predecessor that burned in the Great Fire of 1666. The dome of St Paul's dominated the London skyline for centuries, inspiring the artworks and writing of William Blake , with his 1789 poem " Holy Thursday " referring to 'the high dome of Pauls'. During

14762-455: Was that the small, lightweight reels of microfilm were almost always transported by air, and as such were delivered much more quickly than any surface mail service could have managed. Libraries began using microfilm in the mid-20th century as a preservation strategy for deteriorating newspaper collections. Books and newspapers that were deemed in danger of decay could be preserved on film and thus access and use could be increased. Microfilming

14884-524: Was unveiled on the same day, and is the focal point for the National Service of Remembrance held annually on Remembrance Sunday , the closest Sunday to 11 November. The 1948 Summer Olympics were held at the original Wembley Stadium , while London was still recovering from the war. From the 1940s, London became home to many immigrants, primarily from Commonwealth countries such as Jamaica, India, Bangladesh and Pakistan, making London one of
