92-609: Sher Mandal ( Sher Shah's Pavilion ) is a 16th-century historic Library within the Purana Qila fort located in Delhi , India. Designed in a blend of Indo-islamic , Timurid and Persian architecture, it is the only surviving palace structure within the fort and has become a tourist attraction. Sher Mandal is east of a hamam (Turkish royal bath) towards the southeastern end of Purana Qila , in Delhi, India. The highest point of
184-502: A special library or academic library, for example. Libraries may also be community hubs, where programmes are made available and people engage in lifelong learning. Modern libraries extend their services beyond the physical walls of the building by providing material accessible by electronic means, including from home via the Internet. The services that libraries offer are variously described as library services, information services, or
276-480: A thin section using a method like the Gazzi-Dickinson Method . This yields the relative percentages of quartz, feldspar, and lithic grains and the amount of clay matrix. The composition of a sandstone can provide important information on the genesis of the sediments when used with a triangular Q uartz, F eldspar, L ithic fragment ( QFL diagrams ). However, geologist have not been able to agree on
368-454: A distance of 2.64 metres (8.7 ft). The dados of this storey contain a 12-pointed star, which was considered auspicious by Humayun , despite it being an astronomical numeral. Both storeys have eight alcoves, one on each side; in the lower storey, they are alternately square and semi-octagonal in shape, whilst those of the upper storey are deeper and rectangular in shape. Marbled satkona symbols are present on each exterior spandrel of
460-676: A large library, the card catalogue often filled a large room. The emergence of desktop computers and the Internet , however, has led to the adoption of electronic catalogue databases (often referred to as "webcats" or as online public access catalogues , OPACs), which allow users to search the library's holdings from any location with Internet access. This style of catalogue maintenance is compatible with new types of libraries, such as digital libraries and distributed libraries , as well as older libraries that have been retrofitted . Large libraries may be scattered within multiple buildings across
552-538: A larger facility. Lamba (2019) reinforced this idea by observing that "today's libraries have become increasingly multi-disciplinary, collaborative and networked" and that applying Web 2.0 tools to libraries would "not only connect the users with their community and enhance communication but will also help the librarians to promote their library's activities, services, and products to target both their actual and potential users". Academic libraries are generally located on college and university campuses and primarily serve
644-484: A love of books. One of the most popular programs offered in public libraries are summer reading programs for children, families, and adults. Another popular reading program for children is PAWS TO READ or similar programs where children can read to certified therapy dogs. Since animals are a calming influence and there is no judgment, children learn confidence and a love of reading. Many states have these types of programs: parents need simply ask their librarian to see if it
736-793: A national library, putting less emphasis on the repository character. The first national libraries had their origins in the royal collections of the sovereign or some other supreme body of the state. Many national libraries cooperate within the National Libraries Section of the International Federation of Library Associations and Institutions (IFLA) to discuss their common tasks, define and promote common standards, and carry out projects helping them to fulfill their duties. The national libraries of Europe participate in The European Library which
828-421: A number of palaces described by Khwandamir and Gulbadam Begam in their accounts of Humayun's architecture. Most importantly, Badayuni, in his chronicle of Humayun's death, prominently mentions that the building was constructed by Humayun himself. Ram Nath points to the architectural designs at Sher Mandal as evidence of a homogeneous construction that is consistent with Humayan's style. Stephen Carr , writing in
920-915: A parent organization and may serve only members of that organization. Examples of research libraries include the British Library , the Bodleian Library at Oxford University and the New York Public Library Main Branch on 42nd Street in Manhattan, State Public Scientific Technological Library of the Siberian Branch of the Russian Academy of Science . Digital libraries are libraries that house digital resources, such as text, photographs, and audio. These are curated by digital librarians. In
1012-436: A public body such as a government, an institution (such as a school or museum), a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained experts in finding, selecting, circulating and organising information while interpreting information needs and navigating and analysing large amounts of information with a variety of resources. The area of study
SECTION 10
#17327870602791104-504: A reference library, which does not lend its holdings, or a lending library, which does lend all or some of its holdings. Some extremely large or traditional research libraries are entirely reference in this sense, lending none of their materials; most academic research libraries, at least in the US and the UK, now lend books, but not periodicals or other materials. Many research libraries are attached to
1196-478: A sandstone goes through as the degree of kinetic processing of the sediments increases. Dott's (1964) sandstone classification scheme is one of many such schemes used by geologists for classifying sandstones. Dott's scheme is a modification of Gilbert's classification of silicate sandstones, and it incorporates R.L. Folk's dual textural and compositional maturity concepts into one classification system. The philosophy behind combining Gilbert's and R. L. Folk's schemes
1288-430: A separate room or area for children. They are an educational agency seeking to acquaint the young with the world's literature and to cultivate a love for reading. Their work supplements that of the public schools. Services commonly provided by public libraries may include storytelling sessions for infants, toddlers, preschool children, or after-school programs, all with an intention of developing early literacy skills and
1380-462: A set of boundaries separating regions of the QFL triangle. Visual aids are diagrams that allow geologists to interpret different characteristics of a sandstone. For example, a QFL chart can be marked with a provenance model that shows the likely tectonic origin of sandstones with various compositions of framework grains. Likewise, the stage of textural maturity chart illustrates the different stages that
1472-507: A staff member. Ways in which a library's content is displayed or accessed may have an impact on use. An antiquated or clumsy search system, or staff unwilling or not properly trained to engage their patrons, will limit a library's usefulness. In the public libraries of the United States, beginning in the 19th century, these problems drove the emergence of the library instruction movement, which advocated library user education. One of
1564-424: A town, each having multiple floors, with multiple rooms housing their resources across a series of shelves called bays . Once a user has located a resource within the catalogue, they must then use navigational guidance to retrieve the resource physically, a process that may be assisted through signage, maps, GPS systems, or RFID tagging. Finland has the highest number of registered book borrowers per capita in
1656-445: A twofold classification: Cement is what binds the siliciclastic framework grains together. Cement is a secondary mineral that forms after deposition and during burial of the sandstone. These cementing materials may be either silicate minerals or non-silicate minerals, such as calcite. Sandstone that becomes depleted of its cement binder through weathering gradually becomes friable and unstable. This process can be somewhat reversed by
1748-405: A university. Some items at reference libraries may be historical and even unique. Many lending libraries contain a "reference section", which holds books, such as dictionaries, which are common reference books, and are therefore not lent out. Such reference sections may be referred to as "reading rooms" or "study rooms", which may also include newspapers and periodicals. An example of a reading room
1840-466: Is a collection of books , and possibly other materials and media , that is accessible for use by its members and members of allied institutions. Libraries provide physical (hard copies) or digital (soft copies) materials, and may be a physical location, a virtual space, or both. A library's collection normally includes printed materials which may be borrowed, and usually also includes a reference section of publications which may only be utilized inside
1932-837: Is a distinction that can be recognized in the field . In turn, the distinction between an orthoquartzite and a metaquartzite is the onset of recrystallization of existing grains. The dividing line may be placed at the point where strained quartz grains begin to be replaced by new, unstrained, small quartz grains, producing a mortar texture that can be identified in thin sections under a polarizing microscope. With increasing grade of metamorphism, further recrystallization produces foam texture , characterized by polygonal grains meeting at triple junctions, and then porphyroblastic texture , characterized by coarse, irregular grains, including some larger grains ( porphyroblasts .) Sandstone has been used since prehistoric times for construction, decorative art works and tools. It has been widely employed around
SECTION 20
#17327870602792024-487: Is a service of the Conference of European National Librarians (CENL). A public library provides services to the general public. If the library is part of a countywide library system, citizens with an active library card from around that county can use the library branches associated with the library system. A library can serve only their city, however, if they are not a member of the county public library system. Much of
2116-470: Is an attempt to make the library a more user-driven institution. Despite the importance ascribed to public libraries, their budgets are often cut by legislatures. In some cases, funding has dwindled so much that libraries have been forced to cut their hours and release employees. A reference library does not lend books and other items; instead, they can only be read at the library itself. Typically, such libraries are used for research purposes, for example at
2208-476: Is available at their local library. A national or state library serves as a national repository of information, and has the right of legal deposit , which is a legal requirement that publishers in the country need to deposit a copy of each publication with the library. Unlike a public library, a national library rarely allows citizens to borrow books. Often, their collections include numerous rare, valuable, or significant works. There are wider definitions of
2300-545: Is completely enclosed such that the interior is inaccessible. Nath presumes that it corresponds to a temporary burial site of Humayan, mentioned across contemporary texts. Although the chamber was initially open, it was later closed out of respect, when his corpse was moved to a newly commissioned tomb about two years after his death. The upper storey of Sher Mandal is restricted to visitors. 28°36′31″N 77°14′42″E / 28.60861°N 77.24500°E / 28.60861; 77.24500 Library A library
2392-550: Is composed of quartz or feldspar , because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand , sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topographic features, certain colors of sandstone have become strongly identified with certain regions, such as
2484-435: Is known as library and information science . Library buildings often provide quiet areas for studying, as well as common areas for group study and collaboration, and may provide public facilities for access to their electronic resources, such as computers and access to the Internet . The library's clientele and general services offered vary depending on its type: users of a public library have different needs from those of
2576-523: Is likely formed during eogenesis. Deeper burial is accompanied by mesogenesis , during which most of the compaction and lithification takes place. Compaction takes place as the sand comes under increasing pressure from overlying sediments. Sediment grains move into more compact arrangements, ductile grains (such as mica grains) are deformed, and pore space is reduced. In addition to this physical compaction, chemical compaction may take place via pressure solution . Points of contact between grains are under
2668-824: Is most often an academic or national library , but a large special library may have a research library within its special field, and a very few of the largest public libraries also serve as research libraries. A large university library may be considered a research library; and in North America, such libraries may belong to the Association of Research Libraries . In the United Kingdom, they may be members of Research Libraries UK (RLUK) . Particularly important collections in England may be designated by Arts Council England . A research library can be either
2760-497: Is not lent out. Travelling libraries, such as the early horseback libraries of eastern Kentucky and bookmobiles , are generally of the lending type. Modern libraries are often a mixture of both, containing a general collection for circulation, and a reference collection which is restricted to the library premises. Also, increasingly, digital collections enable broader access to material that may not circulate in print, and enables libraries to expand their collections even without building
2852-454: Is not practical to have available as hard copies. Furthermore, most libraries collaborate with other libraries in exchange of books. Specific course-related resources are usually provided by the library, such as copies of textbooks and article readings held on 'reserve' (meaning that they are loaned out only on a short-term basis, usually a matter of hours). Some academic libraries provide resources not usually associated with libraries, such as

2944-471: Is particularly attractive to younger library users. Digitization of books, particularly those that are out-of-print , in projects such as Google Books provides resources for library and other online users. Due to their holdings of valuable material, some libraries are important partners for search engines such as Google in realizing the potential of such projects and have received reciprocal benefits in cases where they have negotiated effectively. As
3036-431: Is redeposited in the unstrained pore spaces. Mechanical compaction takes place primarily at depths less than 1,000 meters (3,300 ft). Chemical compaction continues to depths of 2,000 meters (6,600 ft), and most cementation takes place at depths of 2,000–5,000 meters (6,600–16,400 ft). Unroofing of buried sandstone is accompanied by telogenesis , the third and final stage of diagenesis. As erosion reduces
3128-443: Is that it is better able to "portray the continuous nature of textural variation from mudstone to arenite and from stable to unstable grain composition". Dott's classification scheme is based on the mineralogy of framework grains, and on the type of matrix present in between the framework grains. In this specific classification scheme, Dott has set the boundary between arenite and wackes at 15% matrix. In addition, Dott also breaks up
3220-672: Is the Hazel H. Ransom Reading Room at the Harry Ransom Center of the University of Texas at Austin , which maintains the papers of literary agent Audrey Wood . A research library is a collection of materials on one or more subjects. A research library supports scholarly or scientific research and will generally include primary as well as secondary sources ; it will maintain permanent collections and attempt to provide access to all necessary materials. A research library
3312-680: The Internet in a number of ways, from creating its own library website to making the contents of its catalogues searchable online . Some specialised search engines such as Google Scholar offer a way to facilitate searching for academic resources such as journal articles and research papers. The Online Computer Library Center allows anyone to search the world's largest repository of library records through its WorldCat online database. Websites such as LibraryThing and Amazon provide abstracts, reviews, and recommendations of books. Libraries provide computers and Internet access to allow people to search for information online. Online information access
3404-413: The Internet . Public and institutional collections and services may be intended for use by people who choose not to—or cannot afford to—purchase an extensive collection themselves, who need material no individual can reasonably be expected to have, or who require professional assistance with their research. Services offered by a library are variously described as library services, information services, or
3496-401: The education of librarians and allied staff include accessibility of the collection, acquisition of materials, arrangement and finding tools, the book trade, the influence of the physical properties of the different writing materials, language distribution, role in education, rates of literacy, budgets, staffing, libraries for specially targeted audiences, architectural merit, patterns of usage,
3588-648: The 21st century, there has been increasing use of the internet to gather and retrieve data. The shift to digital libraries has greatly impacted the way people use physical libraries. Between 2002 and 2004, the average American academic library saw the overall number of transactions decline approximately 2.2%. The University of California Library System saw a 54% decline in circulation between 1991 and 2001 of 8,377,000 books to 3,832,000. Many private businesses and public organizations, including hospitals, churches, museums, research laboratories, law firms, and many government departments and agencies, maintain their own libraries for
3680-618: The Internet age is a matter of growing concern and advocacy; privacy workshops are run by the Library Freedom Project which teach librarians about digital tools (such as the Tor network ) to thwart mass surveillance. Libraries can have several different spaces for different functions such as: Libraries are usually staffed by a combination of professionally trained librarians, paraprofessional staff sometimes called library technicians , and support staff. Some topics related to

However, others have noted a lack of corresponding archaeological and literary evidence to assert the linkage or connect the Qal’a-i Kuhna masjid with Sher Shah's mosque or the pavilion at the Purana Qil'a to be Sher Mandal. Contemporaneous literary descriptions of

3864-572: The ability to check out laptop computers, web cameras, or scientific calculators. Academic libraries offer workshops and courses outside of formal, graded coursework, which are meant to provide students with the tools necessary to succeed in their programs. These workshops may include help with citations, effective search techniques, journal databases, and electronic citation software. These workshops provide students with skills that can help them achieve success in their academic careers (and often, in their future occupations), which they may not learn inside
3956-491: The application of tetraethyl orthosilicate (Si(OC 2 H 5 ) 4 ) which will deposit amorphous silicon dioxide between the sand grains. The reaction is as follows. Pore space includes the open spaces within a rock or a soil. The pore space in a rock has a direct relationship to the porosity and permeability of the rock. The porosity and permeability are directly influenced by the way the sand grains are packed together. Sandstones are typically classified by point-counting
4048-424: The bookshelves also supported the floors, which often were built of translucent blocks to permit the passage of light (but were not transparent, for reasons of modesty). The introduction of electric lights had a huge impact on lighting in libraries . The use of glass floors was largely discontinued, though floors were still often composed of metal grating to allow air to circulate in multi-story stacks. As more space
4140-487: The building (and the fort) are disputed. Sher Mandal was previously believed to have been built by Suri ruler Sher Shah Suri in 1541 as a pleasure resort. The name was first used by the historian Abdullah, author of Tarikh-i Da’udi , who described it as being supposedly left incomplete by Sher Shah. Catherine Asher , a specialist in Indian and Islamic art forms, and others had initially posited that these passages allowed
4232-951: The classroom. The academic library provides a quiet study space for students on campus; it may also provide group study space, such as meeting rooms. In North America, Europe, and other parts of the world, academic libraries are becoming increasingly digitally oriented. The library provides a "gateway" for students and researchers to access various resources, both print/physical and digital. Academic institutions are subscribing to electronic journals databases, providing research and scholarly writing software, and usually provide computer workstations or computer labs for students to access journals, library search databases and portals, institutional electronic resources, Internet access, and course- or task-related software (i.e. word processing and spreadsheet software). Some academic libraries take on new roles, for instance, acting as an electronic repository for institutional scholarly research and academic knowledge, such as
4324-537: The collection and curation of digital copies of students' theses and dissertations. Moreover, academic libraries are increasingly acting as publishers on their own on a not-for-profit basis, especially in the form of fully Open Access institutional publishers. Children's libraries are special collections of books intended for juvenile readers and usually kept in separate rooms of general public libraries. Some children's libraries have entire floors or wings dedicated to them in bigger libraries while smaller ones may have
4416-682: The combination "library and information services", although different institutions and sources define such terminology differently. The term library is based on the Latin word liber for 'book' or 'document', contained in Latin libraria 'collection of books' and librarium 'container for books'. Other modern languages use derivations from Ancient Greek βιβλιοθήκη ( bibliothēkē ), originally meaning 'book container', via Latin bibliotheca ( cf. French bibliothèque or German Bibliothek ). The history of libraries began with
4508-441: The combination "library and information services", although different institutions and sources define such terminology differently. Organizations or departments are often called by one of these names. Most libraries have materials arranged in a specified order according to a library classification system, so that items may be located quickly and collections browsed efficiently. Some libraries have additional galleries beyond
4600-473: The common minerals most resistant to weathering processes at the Earth's surface, as seen in the Goldich dissolution series . Framework grains can be classified into several different categories based on their mineral composition: Matrix is very fine material, which is present within interstitial pore space between the framework grains. The nature of the matrix within the interstitial pore space results in
4692-654: The construction of new libraries or extensions to existing ones, and the development and implementation of outreach services and reading-enhancement services (such as adult literacy and children's programming). Library materials like books, magazines, periodicals, CDs, etc. are managed using a library classification system such as the Dewey Decimal Classification Theory, though libraries will usually adjust their classification system to fit their needs. The International Organization for Standardization (ISO) has published several standards regarding

#17327870602794784-456: The depositional environment, older sand is buried by younger sediments, and it undergoes diagenesis . This mostly consists of compaction and lithification of the sand. Early stages of diagenesis, described as eogenesis , take place at shallow depths (a few tens of meters) and are characterized by bioturbation and mineralogical changes in the sands, with only slight compaction. The red hematite that gives red bed sandstones their color
4876-407: The depth of burial, renewed exposure to meteoric water produces additional changes to the sandstone, such as dissolution of some of the cement to produce secondary porosity . Framework grains are sand-sized (0.0625-to-2-millimeter (0.00246 to 0.07874 in) diameter) detrital fragments that make up the bulk of a sandstone. Most framework grains are composed of quartz or feldspar , which are
4968-518: The destruction of libraries has been critical for conquerors who wish to destroy every trace of the vanquished community's recorded memory. A prominent example of this can be found in the Mongol massacre of the Nizaris at Alamut in 1256 and the torching of their library, "the fame of which", boasts the conqueror Juwayni, "had spread throughout the world". The libraries of Timbuktu were established in
5060-446: The different types of framework grains that can be present in a sandstone into three major categories: quartz, feldspar, and lithic grains. When sandstone is subjected to the great heat and pressure associated with regional metamorphism , the individual quartz grains recrystallize, along with the former cementing material, to form the metamorphic rock called quartzite . Most or all of the original texture and sedimentary structures of
5152-505: The early 1580s, also recorded the existence of Din-panah. Furthermore, the Qal’a-i Kuhna masjid nor the pavilion resemble any of the buildings of Sher Shah. The rectangular plan of the mosque, for instance, with its five bays, inset colonettes and octagonal corner towers, is almost identical to the mosque of Jamali-Kamali, which was begun during the reign of Babur. The double-story pavilion on the other hand, with its octagonal plan, rectangular decorative panels and large chhatri, closely resembles
5244-454: The early leaders was John Cotton Dana . The basic form of library instruction is sometimes known as information literacy . Libraries should inform their users of what materials are available in their collections and how to access that information. Before the computer age, this was accomplished by the card catalogue —a cabinet (or multiple cabinets) containing many drawers filled with index cards that identified books and other materials. In
5336-414: The educational institution. Academic libraries house current, reliable and relevant information resources spread through all the disciplines which serve to assuage the information requirements of students and faculty. In cases where not all books are housed some libraries have E-resources, where they subscribe for a given institution they are serving, in order to provide backups and additional information that
5428-508: The first efforts to organize collections of documents. The first libraries consisted of archives of the earliest form of writing —the clay tablets in cuneiform script discovered in Sumer , some dating back to 2600 BC. Private or personal libraries made up of written books appeared in classical Greece in the 5th century BC. In the 6th century, at the very close of the Classical period ,
5520-523: The fort is occupied by this building. The Mughal emperor Humayun is believed to have used this building as his library. Whilst contemporary historical accounts do not discuss the details of Humayun's death, Abul Fazl , Nizamuddin Ahmad , Firishta and Badayuni , both of whom held distinguished positions at the royal court of Humayun's son Akbar , recorded the event. Fazl wrote that, on 20 January 1556 (other sources give 24 January), Humayun had been on

A library's collection can include books , periodicals , newspapers , manuscripts , films , maps , prints , documents , microform , CDs , cassettes , videotapes , DVDs , Blu-ray Discs , e-books , audiobooks , databases , table games , video games , and other formats. Libraries range widely in size, up to millions of items. Libraries often provide quiet spaces for private studying, common areas to facilitate group study and collaboration, and public facilities for access to their electronic resources and
SECTION 60
#17327870602795704-477: The great libraries of the Mediterranean world remained those of Constantinople and Alexandria . The Fatimids (r. 909–1171) also possessed many great libraries within their domains. The historian Ibn Abi Tayyi’ describes their palace library, which probably contained the largest collection of literature on earth at the time, as a " wonder of the world ". Throughout history, along with bloody massacres,
5796-433: The greatest strain, and the strained mineral is more soluble than the rest of the grain. As a result, the contact points are dissolved away, allowing the grains to come into closer contact. Lithification follows closely on compaction, as increased temperatures at depth hasten deposition of cement that binds the grains together. Pressure solution contributes to cementing, as the mineral dissolved from strained contact points
5888-442: The hardness of individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones , for sharpening blades and other implements. Non-friable sandstone can be used to make grindstones for grinding grain, e.g., gritstone . A type of pure quartz sandstone, orthoquartzite, with more of 90–95 percent of quartz, has been proposed for nomination to

The following is a partial list of some of them: Some patrons may not know how to fully utilize library resources, or feel unease in approaching
6072-466: The materials located within a public library are available for borrowing. The library staff decides upon the number of items patrons are allowed to borrow, as well as the details of borrowing time allotted. Typically, libraries issue library cards to community members wishing to borrow books. Often visitors to a city are able to obtain a public library card. Many public libraries also serve as community organizations that provide free services and events to
6164-402: The monuments at the palace do not support the idea that Sher Shah destroyed (and replaced) Din-panah, as implied by the theories associating Sher-garh with the Purana Qil'a. Abu’l Fazl and Badaoni explicitly mention that Sher Shah established an extensive city between the fortress of Din-panah, which Muhammad Humayun Padshah constructed, and Firozabad. Anthony Monserrate, who visited Delhi during
6256-493: The much lower temperatures and pressures associated with diagenesis of sedimentary rock, but diagenesis has cemented the rock so thoroughly that microscopic examination is necessary to distinguish it from metamorphic quartzite. The term orthoquartzite is used to distinguish such sedimentary rock from metaquartzite produced by metamorphism. By extension, the term orthoquartzite has occasionally been more generally applied to any quartz-cemented quartz arenite . Orthoquartzite (in
6348-464: The narrow sense) is often 99% SiO 2 with only very minor amounts of iron oxide and trace resistant minerals such as zircon , rutile and magnetite . Although few fossils are normally present, the original texture and sedimentary structures are preserved. The typical distinction between a true orthoquartzite and an ordinary quartz sandstone is that an orthoquartzite is so highly cemented that it will fracture across grains, not around them. This
6440-885: The necessity for these services in doubt. Library scholars have acknowledged that libraries need to address the ways that they market their services if they are to compete with the Internet and mitigate the risk of losing users. This includes promoting the information literacy skills training considered vital across the library profession. Many US-based research librarians rely on the ACRL Framework for Information Literacy in order to guide students and faculty in research. However, marketing of services has to be adequately supported financially in order to be successful. This can be problematic for library services that are publicly funded and find it difficult to justify diverting tight funds to apparently peripheral areas such as branding and marketing. The privacy aspect of library usage in
6532-426: The needs of the library. Basic tasks in library management include planning acquisitions (which materials the library should acquire, by purchase or otherwise), classifying and preserving items (especially rare and fragile archival materials such as manuscripts), deaccessioning materials, patron borrowing, and developing and administering library computer systems and technology. More long-term issues include planning
6624-457: The northern and southern walls connecting the two floors. There is a single staircase joining the upper floor with the terrace. Between the two floors there is a band of black slate. The upper storey is protected by small chhajjas (overhanging roofs), above which are cornices , while the chhajjas of the first storey have been destroyed over time. The middle of the terrace contains a spacious octagonal chhatri , with each pillar separated by
6716-421: The number of books in libraries have steadily increased since their inception, the need for compact storage and access with adequate lighting has grown. The stack system involves keeping a library's collection of books in a space separate from the reading room. This arrangement arose in the 19th century. Book stacks quickly evolved into a fairly standard form in which the cast iron and steel frameworks supporting
6808-457: The premises. Resources such as commercial releases of films, television programmes, other video recordings, radio, music and audio recordings may be available in many formats. These include DVDs , Blu-rays , CDs , cassettes , or other applicable formats such as microform . They may also provide access to information, music or other content held on bibliographic databases . Libraries can vary widely in size and may be organised and maintained by
6900-638: The product of physical and chemical weathering of bedrock. Weathering and erosion are most rapid in areas of high relief, such as volcanic arcs , areas of continental rifting , and orogenic belts . Eroded sand is transported by rivers or by the wind from its source areas to depositional environments where tectonics has created accommodation space for sediments to accumulate. Forearc basins tend to accumulate sand rich in lithic grains and plagioclase . Intracontinental basins and grabens along continental margins are also common environments for deposition of sand.

Rock formations composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs . Quartz-bearing sandstone can be changed into quartzite through metamorphism , usually related to tectonic compression within orogenic belts . Sandstones are clastic in origin (as opposed to either organic , like chalk and coal , or chemical , like gypsum and jasper ). The silicate sand grains from which they form are
7360-411: The role of libraries in a nation's cultural heritage, and the role of government, church, or private sponsorship. Since the 1960s, issues of computerization and digitization have arisen.

Humayun purportedly sat on the steps to pray and, as he stood up, one of his legs became entangled with his robe, resulting his fall down
7544-417: The sandstone are erased by the metamorphism. The grains are so tightly interlocked that when the rock is broken, it fractures through the grains to form an irregular or conchoidal fracture. Geologists had recognized by 1941 that some rocks show the macroscopic characteristics of quartzite, even though they have not undergone metamorphism at high pressure and temperature. These rocks have been subject only to
7636-444: The sides supporting the four arches and a vaulted ceiling. The interiors bear exquisite stalactite designs and other decorations of glazed tiles and incised stucco . The walls are paneled with encaustic tiles to a height of about three feet from the floor. The rest of the wall, up to the ceiling, is ornamented with paintings of flowers and fancy patterns. The interior of the arches are scantily ornamented with marble. The lower storey

Ram Nath, too, noted the structure as lacking any minimal resemblance to an unfinished palace, as well as a lack of shelves, niches or any other feature that might have justified its use as a library. Nath, in light of its geographical position and circumstantial literary corpus, proposed that it
7912-623: The students and faculty of that and other academic institutions. Some academic libraries, especially those at public institutions, are accessible to members of the general public in whole or in part. Library services are sometimes extended to the general public at a fee; some academic libraries create such services in order to enhance literacy levels in their communities. Academic libraries are libraries that are hosted in post-secondary educational institutions, such as colleges and universities. Their main functions are to provide support in research, consultancy and resource linkage for students and faculty of

There exists a cruciform chamber in the upper storey—a single square-shaped room at the centre, which opens out into four smaller rooms aligned with four of the alcoves. These arms in turn are linked to form an ambulatory . The chamber has semi-vaulted soffits on
8096-476: The use of their employees in doing specialized research related to their work. Depending on the particular institution, special libraries may or may not be accessible to the general public or elements thereof. Sandstone Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks . Most sandstone
8188-626: The world in constructing temples, churches, homes and other buildings, and in civil engineering . Although its resistance to weathering varies, sandstone is easy to work. That makes it a common building and paving material, including in asphalt concrete . However, some types that have been used in the past, such as the Collyhurst sandstone used in North West England , have had poor long-term weather resistance, necessitating repair and replacement in older buildings. Because of
8280-412: The world. Over half of Finland's population are registered borrowers. In the US, public library users have borrowed on average roughly 15 books per user per year from 1856 to 1978. From 1978 to 2004, book circulation per user declined approximately 50%.
