The Research Libraries Group ( RLG ) was a U.S. -based library consortium that existed from 1974 until its merger with the OCLC library consortium in 2006. RLG developed the Eureka interlibrary search engine, the RedLightGreen database of bibliographic descriptions, and ArchiveGrid , a database containing descriptions of archival collections. It also developed a framework known as the "RLG Conspectus" for evaluating research library collections, which evolved into a set of descriptors used in library collection policy statements, last updated in 1997. The Library of Congress used the conspectus in 2015 in revising its own collection policy statement, and decided to retain this resource on its website, as a helpful scale for judging an academic collection's depth.
55-779: RLG was founded in 1974 by four major research libraries : the New York Public Library and the university libraries of Columbia , Harvard and Yale ; it was incorporated as a not-for-profit membership organization in 1975. RLG was established in part due to dissatisfaction among research institutions with the record-keeping of the OCLC library consortium. In 1978 RLG moved its offices, which were originally in Branford, Connecticut (not far from New Haven), to Stanford University ; and it adopted Stanford Library 's BALLOTS computerized processing system. This system evolved into
110-515: A writing surface . It was made from the pith of the papyrus plant, Cyperus papyrus , a wetland sedge . Papyrus (plural: papyri or papyruses ) can also refer to a document written on sheets of such material, joined side by side and rolled up into a scroll , an early form of a book. Papyrus was first known to have been used in Egypt (at least as far back as the First Dynasty ), as
165-463: A few days to as short as a few hours. Patrons can also gain access to periodicals and journals that require paid subscriptions through their libraries which they can use to access primary research materials. A research library is often connected to the services of the university related to scholarly communication , such as support for open access journals run by the institution and the operation of an institutional repository , as well as support for
220-409: A hard surface with their edges slightly overlapping, and then another layer of strips is laid on top at right angles. The strips may have been soaked in water long enough for decomposition to begin, perhaps increasing adhesion, but this is not certain. The two layers possibly were glued together. While still moist, the two layers were hammered together, mashing the layers into a single sheet. The sheet
275-624: A loanword of unknown (perhaps Pre-Greek ) origin. Greek has a second word for it, βύβλος ( byblos ), said to derive from the name of the Phoenician city of Byblos . The Greek writer Theophrastus , who flourished during the 4th century BCE, uses papyros when referring to the plant used as a foodstuff and byblos for the same plant when used for nonfood products, such as cordage, basketry, or writing surfaces. The more specific term βίβλος biblos , which finds its way into English in such words as 'bibliography', 'bibliophile', and 'bible', refers to
330-453: A long roll, or scroll, was required to create large-volume texts. Papyrus had the advantage of being relatively cheap and easy to produce, but it was fragile and susceptible to both moisture and excessive dryness. Unless the papyrus was of perfect quality, the writing surface was irregular, and the range of media that could be used was also limited. Papyrus was gradually overtaken in Europe by
385-681: A matter of decades; a 200-year-old papyrus was considered extraordinary. Imported papyrus once commonplace in Greece and Italy has since deteriorated beyond repair, but papyri are still being found in Egypt; extraordinary examples include the Elephantine papyri and the famous finds at Oxyrhynchus and Nag Hammadi . The Villa of the Papyri at Herculaneum , containing the library of Lucius Calpurnius Piso Caesoninus , Julius Caesar 's father-in-law,
440-436: A rival writing surface that rose in prominence known as parchment , which was made from animal skins . By the beginning of the fourth century A.D., the most important books began to be manufactured in parchment, and works worth preserving were transferred from papyrus to parchment. Parchment had significant advantages over papyrus, including higher durability in moist climates and being more conducive to writing on both sides of
495-447: Is able to acquire and maintain materials that are not easily available through traditional acquisition methods. Research libraries can be either reference libraries , which do not lend their holdings, or lending libraries , which do lend all or some of their holdings. Some extremely large or traditional research libraries are entirely reference in this sense, lending none of their material; most academic research libraries , at least in
550-654: Is conducted by their librarians on their topics of choice. Libraries first appeared in Southwest Asia more than 5,000 years ago as repositories to store written resources for retrieval, often written on materials like bamboo, clay, and later papyrus . The most durable of these materials was clay, and tablets made of clay are the most common artifacts retrieved from ancient library sites. Many great civilizations built libraries which contained knowledge and information that were accumulated over years, sometimes centuries, and from across regions. The oldest known library in
605-442: Is of highly rot-resistant cellulose , but storage in humid conditions can result in molds attacking and destroying the material. Library papyrus rolls were stored in wooden boxes and chests made in the form of statues. Papyrus scrolls were organized according to subject or author and identified with clay labels that specified their contents without having to unroll the scroll. In European conditions, papyrus seems to have lasted only

It is the United States Congress' official research library and is the oldest federal cultural institution in the country, having been founded in 1800. It contains more than 170 million items that cover a wide range of subjects from across the world and in 470 different languages. The library has offices abroad through which it
715-401: Is that it enables greater automation of workflows within libraries which ensures that they become more streamlined. These increased efficiencies ensure libraries and their librarians are able to provide the highest quality service possible. Papyrus Papyrus ( / p ə ˈ p aɪ r ə s / pə- PY -rəs ) is a material similar to thick paper that was used in ancient times as
770-680: The Cambridge Antiquarian Society , one of the Papyri Graecae Magicae V, translated into English with commentary in 1853. Papyrus was made in several qualities and prices. Pliny the Elder and Isidore of Seville described six variations of papyrus that were sold in the Roman market of the day. These were graded by quality based on how fine, firm, white, and smooth the writing surface was. Grades ranged from
825-587: The Islamic world , which originally learned of it from the Chinese. By the 12th century, parchment and paper were in use in the Byzantine Empire , but papyrus was still an option. Until the middle of the 19th century, only some isolated documents written on papyrus were known, and museums simply showed them as curiosities. They did not contain literary works. The first modern discovery of papyri rolls
880-548: The Merovingian chancery was with a document from 692 A.D., though it was known in Gaul until the middle of the following century. The latest certain dates for the use of papyrus in Europe are 1057 for a papal decree (typically conservative, all papal bulls were on papyrus until 1022), under Pope Victor II , and 1087 for an Arabic document. Its use in Egypt continued until it was replaced by less expensive paper introduced by
935-566: The 18th century, a library of ancient papyri was found in Herculaneum , ripples of expectation spread among the learned men of the time. However, since these papyri were badly charred, their unscrolling and deciphering are still going on today. Papyrus was made from the stem of the papyrus plant, Cyperus papyrus . The outer rind was first removed, and the sticky fibrous inner pith is cut lengthwise into thin strips about 40 cm (16 in) long. The strips were then placed side by side on
990-679: The U.S., and by 1989 reached 100 members. In 1992 the British Library became the first member outside North America. As of 2003, RLG's membership included over 160 research institutions in 15 different countries. In July 2006, RLG and OCLC officially initiated a merging of their organizations and resources. The completion of this process took place over a five-year period, through June 2011. RLG's catalog became part of OCLC's WorldCat . Its programs joined with OCLC Research to become OCLC Programs and Research. Eureka databases were migrated to OCLC's FirstSearch service. An RLG staff of reduced size
1045-478: The U.S., now lend books, but not periodicals or other material. Books available in research libraries can include textbooks, journals and rare manuscripts. As the contents of research libraries are so focused, there can sometimes be a high demand for certain book titles. To ensure that as many patrons as possible can have access to the books they need, libraries have reserve collections, the books of which are only available for short-term loans. These loans can range from
1100-538: The advent of technology, this has evolved to include CDs, DVDs, Ebooks, audiobooks and online research catalogues. Research library collections are focused on one or more subjects or fields of study and the material available on those topics are typically more extensive and in-depth than that found in public lending libraries. Institutions such as universities may have multiple research libraries on campus, each dedicated to different faculties or subjects. Research libraries may also publish their own scholarly research which
1155-422: The appropriate databases or materials or in some cases obtaining these materials from external sources for them. With the changing role of libraries, research librarians' roles have evolved to include more than just selecting and maintaining the library's offerings and books, and helping patrons locate the items of their choice. Today, librarians must also be technologically savvy so they can teach users how to use
SECTION 20
#17327733641321210-752: The basis of historical research. Having a rare book in a library's collection is very prestigious and is often indicative of the library's high standards for materials. Libraries may also have archives of old photographs, films, musical scores and even artwork. They often also have archives of old newspapers and periodicals. Newspapers are often accessible through microfiche machines, which are used to view images of back issues of such publications. Research libraries also often provide patrons with basic technological equipment such as computers, scanners and printers to aid them in their work. These libraries frequently collaborate with one another to share resources through inter-library loans. This enables each library to meet
1265-460: The early 2010s and has been accelerated due to the COVID-19 pandemic when many libraries across the world were physically closed forcing patrons to rely solely on their electronic offerings. Libraries have had to update their technological infrastructure in order to keep up with the new demands of the public. The first step the average person takes when they conduct research is no longer visiting
1320-459: The form of codices akin to the modern book. This may have been mimicking the book-form of codices created with parchment . Early Christian writers soon adopted the codex form, and in the Greco-Roman world, it became common to cut sheets from papyrus rolls to form codices. Codices were an improvement on the papyrus scroll, as the papyrus was not pliable enough to fold without cracking, and
1375-608: The greatest ancient libraries in the world was the Library of Ashurbanipal , which was founded in the 7th century BC in Niveah, near present-day Iraq , by the Assyrian king Ashurbanipal . The library contained around 30,000 cuneiform tablets written in multiple languages pertaining to scholarly texts, archival documents and religious materials along with some works of ancient literature. The king sent his scribes to other libraries in
1430-484: The inner bark of the papyrus plant. Papyrus is also the etymon of 'paper', a similar substance. In the Egyptian language , papyrus was called wadj ( w3ḏ ), tjufy ( ṯwfy ) , or djet ( ḏt ). The word for the material papyrus is also used to designate documents written on sheets of it, often rolled up into scrolls. The plural for such documents is papyri. Historical papyri are given identifying names – generally
1485-418: The librarians affiliated with that institution. Digitization projects are often intensive and long-drawn. Librarians need to identify which materials should be digitized and the priority in which they should be digitized. They also need to ascertain what formats will be most suitable for the materials and the patrons, raise the necessary funds and obtain the rights to digitize the items. They then need to prepare
1540-415: The libraries. These resources are often of high quality and are from trusted sources and publishers. They also catalogue and organize the books and resources, maintain and repair books as required. Librarians can also work with colleagues in other institutions to share resources and better the relationships between institutions. Librarians who work in research libraries often have in-depth knowledge of
1595-457: The library at its height had up to 400,000 scrolls, though there is uncertainty regarding the exact number and how many scrolls were original works, as some of these may have been copies. The works collected covered a wide range of topics including works by Homer , Herodotus , Plato , and Aristotle . The library drew scholars from across the world and led to Alexandria being known as a hub for knowledge and learning. The US Library of Congress
1650-404: The library but searching for information online. Patrons will obtain a basic understanding of their topic and identify the books or materials they need before ever setting foot in a library. They can also identify which libraries will provide them the most convenient access to these materials through online archives and catalogues. This is what makes effective digitization projects in libraries and
1705-617: The library has the materials they need and when and how these materials will be available for their use. Many libraries also have interlinked systems that enable patrons to reserve and borrow books from affiliated libraries, effectively increasing their collection size while keeping costs down. This can make it possible for libraries to offer resources that have a narrow appeal and a low demand but that could still be useful for patrons to access. Libraries are also required to be more efficient to meet both consumer demand and to keep up with continuing budget cuts. One benefit of increasing digitization

1760-470: The library's electronic systems. Many librarians conduct their own independent research on topics pertaining to a library's field or on the topic of libraries themselves. When the library is affiliated with an academic institution, librarians may even have quotas on how much research they must complete and how many papers they should publish. Oftentimes, these librarians have to meet their quotas in order to be eligible for promotions or even tenure positions at
1815-435: The library. Librarians' research can help to improve the level of service offered by the staff of the institution by increasing their knowledge of the investigative process. The research conducted may also support the operations of the library. Librarians also spearhead the digitization projects of any primary research sources that the library might have. These sources are typically the result of research projects conducted by
1870-440: The long strip scrolls required, several such sheets were united and placed so all the horizontal fibres parallel with the roll's length were on one side and all the vertical fibres on the other. Normally, texts were first written on the recto , the lines following the fibres, parallel to the long edges of the scroll. Secondarily, papyrus was often reused, writing across the fibres on the verso . One source used for determining
1925-571: The maintenance of accurate online catalogues crucial for libraries' continued survival. Libraries may also have functions on their websites which enable patrons to email librarians with questions directly to obtain answers in a quick and efficient manner and also ensure that questions will be addressed by the most qualified party. Libraries are now required to have extensive digital collections which comprise electronic journals, Ebooks and virtual reference services. They must also make their catalogues available online for users to quickly determine whether
1980-416: The method by which papyrus was created in antiquity is through the examination of tombs in the ancient Egyptian city of Thebes , which housed a necropolis containing many murals displaying the process of papyrus-making. The Roman commander Pliny the Elder also describes the methods of preparing papyrus in his Naturalis Historia . In a dry climate , like that of Egypt, papyrus is stable, formed as it
2035-886: The name of the discoverer, first owner, or institution where they are kept – and numbered, such as " Papyrus Harris I ". Often an abbreviated form is used, such as "pHarris I". These documents provide important information on ancient writings; they give us the only extant copy of Menander , the Egyptian Book of the Dead , Egyptian treatises on medicine (the Ebers Papyrus ) and on surgery (the Edwin Smith papyrus ), Egyptian mathematical treatises (the Rhind papyrus ), and Egyptian folk tales (the Westcar Papyrus ). When, in
2090-510: The needs of more patrons while keeping their costs down. Libraries may also collaborate to share the costs features such as licensing information sources. This is especially important today, with libraries being required to offer more services for their patrons with fewer resources. Librarians at research libraries are responsible for curating the library's collections. They identify the best books and resources by reading catalogues, publishers' announcements and book reviews, and acquire them for
2145-491: The online database RLIN (Research Libraries Information Network), which notably included bibliographic data representing JACKPHY (non-Roman) scripts. RLIN was generally used only by library specialists; in 1993 RLG developed Eureka as a user-friendly interface for use by non-librarians. In 1988 RLG moved its offices to Mountain View, California . In the meantime its membership had expanded to include other research libraries in
2200-464: The original documents, have them scanned or otherwise converted and ensure that all the necessary metadata is added. They then have to perform quality checks to ensure that the material is of the highest quality and fit to be released to the public. With the rapid advancement of technology and the advent of the digital age, consumers expectations are changing and libraries are being required to improve their digital infrastructure. This phenomenon began in
2255-542: The papyrus plant was once abundant across the Nile Delta . It was also used throughout the Mediterranean region. Apart from writing material, ancient Egyptians employed papyrus in the construction of other artifacts , such as reed boats , mats , rope , sandals , and baskets . Papyrus was first manufactured in Egypt as far back as the third millennium BCE. The earliest archaeological evidence of papyrus

2310-875: The public who wish to gain in-depth knowledge on that particular topic. Research libraries face a unique challenge of making research materials accessible and available to patrons. They also need to ensure there are no copyright-related issues with their materials, ensure that as many materials as possible are open access, and ensure all their materials are reliably sourced. Some specialized research libraries could include those affiliated to governmental organizations which may hold documents of historical, legal or political import, or music libraries which will have books and journals on music, as well as films and recordings for musicians to access. Research libraries will generally have materials that are typically non-fiction and scholarly. These traditionally included books, periodicals, journals, newspapers, manuscripts and cassette tapes. With
2365-572: The region to record their contents to create a register of contents. Probably the most renowned library in the ancient world was the Great Library of Alexandria , in Egypt . The library was part of the royal complex that included the research institution known as the Mouseion , and is believed to have been established during the reigns of Ptolemy I Soter (367–283 BC) and his son Ptolemy II Philadelphus (285–246 BC). There are report that
2420-441: The subjects that are the focus of the institutions in which they work. They are therefore able to answer more specific topical queries that patrons might have while also giving advice on the best resources to access for the necessary information. They conduct informational or reference interviews with patrons to ascertain what information they are looking for, and the purpose behind their research. This can help them to direct users to
2475-408: The superfine Augustan, which was produced in sheets of 13 digits (10 inches) wide, to the least expensive and most coarse, measuring six digits (four inches) wide. Materials deemed unusable for writing or less than six digits were considered commercial quality and were pasted edge to edge to be used only for wrapping. The English word "papyrus" derives, via Latin , from Greek πάπυρος ( papyros ),
2530-488: The surface. The main advantage of papyrus had been its cheaper raw material — the papyrus plant is easy to cultivate in a suitable climate and produces more writing material than animal hides (the most expensive books, made from foetal vellum would take up to dozens of bovine fetuses to produce). However, as trade networks declined, the availability of papyrus outside the range of the papyrus plant became limited and it thus lost its cost advantage. Papyrus' last appearance in
2585-556: The tourist trade was developed in 1962 by the Egyptian engineer Hassan Ragab using plants that had been reintroduced into Egypt in 1872 from France. Both Sicily and Egypt have centres of limited papyrus production. Papyrus is still used by communities living in the vicinity of swamps, to the extent that rural householders derive up to 75% of their income from swamp goods. Particularly in East and Central Africa, people harvest papyrus, which
2640-545: The usage of other institutions' repositories and open archives through discovery tools and academic search engines like BASE , CORE and Unpaywall . Rare books and manuscripts are often very valuable and can sometimes be fragile. These are often not available for loan, and can only be accessed within the library and sometimes under the supervision of the librarian. Rare books are those that were printed before 1850 and of which very few copies still exist today. They are highly valuable for research purposes as they often form
2695-579: The wild. During the 1920s, when Egyptologist Battiscombe Gunn lived in Maadi , outside Cairo, he experimented with the manufacture of papyrus, growing the plant in his garden. He beat the sliced papyrus stalks between two layers of linen and produced successful examples of papyrus, one of which was exhibited in the Egyptian Museum in Cairo. The modern technique of papyrus production used in Egypt for
2750-530: The world was excavated in Ebla in northern Syria. Excavation of the site of the ancient city began in 1964 and archeologists have since uncovered more than 20,000 clay tablets that documented the economic and cultural life of the city's residents. Archives dating back to 3000 BC were also discovered in 1975. The library also contained scientific records and observations on topics such as zoology , mineralogy , and information on Ebla's business and tax issues. One of
2805-650: Was excavated in 2012 and 2013 at Wadi al-Jarf , an ancient Egyptian harbor located on the Red Sea coast. These documents, the Diary of Merer , date from c. 2560 –2550 BCE (end of the reign of Khufu ). The papyrus rolls describe the last years of building the Great Pyramid of Giza . For multiple millennia, papyrus was commonly rolled into scrolls as a form of storage. However, at some point late in its history, papyrus began being collected together in

Scholarly investigations began with the Dutch historian Caspar Jacob Christiaan Reuvens (1793–1835). He wrote about the content of the Leyden papyrus , published in 1830. The first publication has been credited to the British scholar Charles Wycliffe Goodwin (1817–1878), who published for
2915-472: Was preserved by the eruption of Mount Vesuvius but has only been partially excavated. Sporadic attempts to revive the manufacture of papyrus have been made since the mid-18th century. Scottish explorer James Bruce experimented in the late 18th century with papyrus plants from Sudan , for papyrus had become extinct in Egypt. Also in the 18th century, Sicilian Saverio Landolina manufactured papyrus at Syracuse , where papyrus plants had continued to grow in
2970-1047: Was relocated from Mountain View to San Mateo, California . Research library A research library is a library that contains an in-depth collection of material on one or several subjects. A research library will generally include an in-depth selection of materials on a particular topic or set of topics and contain primary sources as well as secondary sources . Research libraries are established to meet research needs and, as such, are stocked with authentic materials with quality content. Research libraries are typically attached to academic or research institutions that specialize in that topic and serve members of that institution. Large university libraries are considered research libraries, and often contain many specialized branch research libraries. The libraries provide research materials for students and staff of these organizations to use and can also publish and carry literature produced by these institutions and make them available to others. Research libraries could also be accessible to members of

Sheets, or Mollema, could be cut to fit the obligatory size or glued together to create a longer roll. The point where the Mollema are joined with glue is called the kollesis. A wooden stick would be attached to the last sheet in a roll, making it easier to handle. To form
