OCLC
–
The Online Computer Library Center is a US-based nonprofit cooperative organization dedicated to the public purposes of furthering access to the worlds information and reducing information costs. It was founded in 1967 as the Ohio College Library Center, OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded mainly by the fees that libraries have to pay for its services, the group first met on July 5,1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization. The group hired Frederick G. Kilgour, a former Yale University medical school librarian, Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The goal of network and database was to bring libraries together to cooperatively keep track of the worlds information in order to best serve researchers and scholars. The first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26,1971 and this was the first occurrence of online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data, between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the structure was again modified to accommodate participation from outside the United States. As OCLC expanded services in the United States outside of Ohio, it relied on establishing strategic partnerships with networks, organizations that provided training, support, by 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on OCLC Members Council, in early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic, abstract and full-text information to anyone, OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from public and private libraries worldwide. org, in October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. The Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988, a browser for books with their Dewey Decimal Classifications was available until July 2013, it was replaced by the Classify Service. S. The reference management service QuestionPoint provides libraries with tools to communicate with users and this around-the-clock reference service is provided by a cooperative of participating global libraries. OCLC has produced cards for members since 1971 with its shared online catalog. OCLC commercially sells software, e. g. CONTENTdm for managing digital collections, OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications and these publications, including journal articles, reports, newsletters, and presentations, are available through the organizations website. The most recent publications are displayed first, and all archived resources, membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding

Authority control
–
The word authority in authority control derives from the idea that the names of people, places, things, and concepts are authorized, i. e. they are established in one particular form. The unique header can guide users to all relevant information including related or collocated subjects, accordingly, authority control is an example of controlled vocabulary and of bibliographic control. Subject headings from the Library of Congress fulfill a similar to authority records. As time passes, information changes, prompting needs for reorganization, Authority control helps researchers get a handle on a specific subject with less wasted effort. A well-designed digital catalog/database enables a researcher to query a few words of an entry to bring up the established term or phrase, thus improving accuracy. It can be used in conjunction with keyword searching using and or not or or or other Boolean operators on a web browser and it increases chances that a given search will return relevant items. The process of authority control is not only of great help to researchers searching for a subject to study. Cataloguers can use authority records when trying to categorize new items, since they can see which records have already been catalogued and it enables cataloguers to detect and correct errors. In some instances, software programs support workers tasked with maintaining the catalog to do ongoing tasks such as automated clean-up and it helps creators and users of metadata. It can help catch errors caused by typos or misspellings which can accumulate over time. For example, machines can catch such as Elementary school techers. Sometimes within a catalog there are different names or spellings for only one person or subject and this can bring confusion since researchers may miss some information. Authority control is used by cataloguers to collocate materials that belong together. Records are used to establish uniform titles which collocate all versions of a work under one unique heading even when such versions are issued under different titles. In an online catalog, various entries might look like the following. Diana, Princess of Wales, 1961-1997 Diana, Princess of Wales 1961-1997 Diana, Princess of Wales, 1961-1997 DIANA, PRINCESS OF WALES, Diana, Princess of Wales, - Iconography. These different terms describe the same person, one international effort to prevent such confusion is the Virtual International Authority File which is a collaborative attempt to provide a single heading for a particular subject. The idea is to create a single virtual authority file

Library of Congress
–
The Library of Congress is the research library that officially serves the United States Congress and is the de facto national library of the United States. It is the oldest federal cultural institution in the United States, the Library is housed in three buildings on Capitol Hill in Washington, D. C. it also maintains the Packard Campus in Culpeper, Virginia, which houses the National Audio-Visual Conservation Center. The Library of Congress claims to be the largest library in the world and its collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 450 languages. Two-thirds of the books it acquires each year are in other than English. The Library of Congress moved to Washington in 1800, after sitting for years in the temporary national capitals of New York. John J. Beckley, who became the first Librarian of Congress, was two dollars per day and was required to also serve as the Clerk of the House of Representatives. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s, most of the original collection had been destroyed by the British in 1814, during the War of 1812. To restore its collection in 1815, the bought from former president Thomas Jefferson his entire personal collection of 6,487 books. After a period of growth, another fire struck the Library in its Capitol chambers in 1851, again destroying a large amount of the collection. The Library received the right of transference of all copyrighted works to have two copies deposited of books, maps, illustrations and diagrams printed in the United States. It also began to build its collections of British and other European works and it included several stories built underground of steel and cast iron stacks. Although the Library is open to the public, only high-ranking government officials may check out books, the Library promotes literacy and American literature through projects such as the American Folklife Center, American Memory, Center for the Book, and Poet Laureate. James Madison is credited with the idea for creating a congressional library, part of the legislation appropriated $5,000 for the purchase of such books as may be necessary for the use of Congress. And for fitting up an apartment for containing them. Books were ordered from London and the collection, consisting of 740 books and 3 maps, was housed in the new Capitol, as president, Thomas Jefferson played an important role in establishing the structure of the Library of Congress. The new law also extended to the president and vice president the ability to borrow books and these volumes had been left in the Senate wing of the Capitol. One of the only congressional volumes to have survived was a government account book of receipts and it was taken as a souvenir by a British Commander whose family later returned it to the United States government in 1940. Within a month, former president Jefferson offered to sell his library as a replacement

German National Library
–
The German National Library is the central archival library and national bibliographic centre for the Federal Republic of Germany. The German National Library maintains co-operative external relations on a national and international level, for example, it is the leading partner in developing and maintaining bibliographic rules and standards in Germany and plays a significant role in the development of international library standards. The cooperation with publishers is regulated by law since 1935 for the Deutsche Bücherei Leipzig, duties are shared between the facilities in Leipzig and Frankfurt am Main, with each center focusing its work in specific specialty areas. A third facility has been the Deutsches Musikarchiv Berlin, which deals with all music-related archiving, since 2010 the Deutsches Musikarchiv is also located in Leipzig as an integral part of the facility there. During the German revolutions of 1848 various booksellers and publishers offered their works to the Frankfurt Parliament for a parliamentary library, the library, led by Johann Heinrich Plath, was termed the Reichsbibliothek. After the failure of the revolution the library was abandoned and the stock of books already in existence was stored at the Germanisches Nationalmuseum in Nuremberg. In 1912, the town of Leipzig, seat of the annual Leipzig Book Fair, the Kingdom of Saxony, starting January 1,1913, all publications in German were systematically collected. In the same year, Dr. Gustav Wahl was elected as the first director, the Federal state representatives of the book trade in the American zone agreed to the proposal. The city of Frankfurt agreed to support the planned archive library with personnel, the US military government gave its approval. The Library began its work in the room of the former Rothschild library. As a result, there were two libraries in Germany, which assumed the duties and function of a library for the later GDR. Two national bibliographic catalogues almost identical in content were published annually, with the reunification of Germany on 3 October 1990, the Deutsche Bücherei Leipzig and the Deutsche Bibliothek Frankfurt am Main were merged into a new institution, The German Library. The Law regarding the German National Library came into force on 29 June 2006, the expansion of the collection brief to include online publications set the course for collecting, cataloguing and storing such publications as part of Germanys cultural heritage. The Librarys highest management body, the Administrative Council, was expanded to include two MPs from the Bundestag, the law also changed the name of the library and its buildings in Leipzig, Frankfurt am Main and Berlin to Deutsche Nationalbibliothek. In July 2000, the DMA also assumed the role as repository for GEMA, Gesellschaft für musikalische Aufführungs- und mechanische Vervielfältigungsrechte, since then, music publishers only have to submit copies to DMA, which covers both national archiving and copyright registration. The 210,000 works of printed music previously held by GEMA were transferred to DMA, additionally included in the project were 30 German-language emigrant publications German-language exile journals 1933–1945, consisting of around 100,000 pages. These collections were put online in 2004 and were some of the most frequently visited sites of the German National Library, in June 2012 the German National Library discontinued access to both collections on its website for legal reasons. The digitised versions are then available for use in the reading rooms of the German National Library in Leipzig and Frankfurt am Main only

Wikipedia
–
Wikipedia is a free online encyclopedia that aims to allow anyone to edit articles. Wikipedia is the largest and most popular reference work on the Internet and is ranked among the ten most popular websites. Wikipedia is owned by the nonprofit Wikimedia Foundation, Wikipedia was launched on January 15,2001, by Jimmy Wales and Larry Sanger. Sanger coined its name, a portmanteau of wiki and encyclopedia, There was only the English language version initially, but it quickly developed similar versions in other languages, which differ in content and in editing practices. With 5,377,348 articles, the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias, in 2005, Nature published a peer review comparing 42 science articles from Encyclopædia Britannica and Wikipedia, and found that Wikipedias level of accuracy approached Encyclopædia Britannicas. Other collaborative online encyclopedias were attempted before Wikipedia, but none were so successful, Wikipedia began as a complementary project for Nupedia, a free online English-language encyclopedia project whose articles were written by experts and reviewed under a formal process. Nupedia was founded on March 9,2000, under the ownership of Bomis and its main figures were Jimmy Wales, the CEO of Bomis, and Larry Sanger, editor-in-chief for Nupedia and later Wikipedia. Nupedia was licensed initially under its own Nupedia Open Content License, while Wales is credited with defining the goal of making a publicly editable encyclopedia, Sanger is credited with the strategy of using a wiki to reach that goal. On January 10,2001, Sanger proposed on the Nupedia mailing list to create a wiki as a project for Nupedia. Wikipedia was launched on January 15,2001, as a single English-language edition at www. wikipedia. com, Wikipedias policy of neutral point-of-view was codified in its first months. Otherwise, there were few rules initially and Wikipedia operated independently of Nupedia. Originally, Bomis intended to make Wikipedia a business for profit, Wikipedia gained early contributors from Nupedia, Slashdot postings, and web search engine indexing. By August 8,2001, Wikipedia had over 8,000 articles, on September 25,2001, Wikipedia had over 13,000 articles. By the end of 2001, it had grown to approximately 20,000 articles and 18 language editions and it had reached 26 language editions by late 2002,46 by the end of 2003, and 161 by the final days of 2004. Nupedia and Wikipedia coexisted until the servers were taken down permanently in 2003. Citing fears of commercial advertising and lack of control in Wikipedia and these moves encouraged Wales to announce that Wikipedia would not display advertisements, and to change Wikipedias domain from wikipedia. com to wikipedia. org. Around 1,800 articles were added daily to the encyclopedia in 2006, a team at the Palo Alto Research Center attributed this slowing of growth to the projects increasing exclusivity and resistance to change. Others suggest that the growth is flattening naturally because articles that could be called low-hanging fruit—topics that clearly merit an article—have already been created, the Wall Street Journal cited the array of rules applied to editing and disputes related to such content among the reasons for this trend

Wikidata
–
Wikidata is a collaboratively edited knowledge base operated by the Wikimedia Foundation. It is intended to provide a source of data which can be used by Wikimedia projects such as Wikipedia. This is similar to the way Wikimedia Commons provides storage for files and access to those files for all Wikimedia projects. Wikidata is powered by the software Wikibase, Wikidata is a document-oriented database, focused on items. Each item represents a topic and is identified by a number, prefixed with the letter Q—for example. This enables the basic information required to identify the topic the item covers to be translated without favouring any language, information is added to items by creating statements. Statements take the form of pairs, with each statement consisting of a property. The creation of the project was funded by donations from the Allen Institute for Artificial Intelligence, the Gordon and Betty Moore Foundation, at this time, only the first phase was available. Historically, a Wikipedia article would include a list of links, being links to articles on the same topic in other editions of Wikipedia. Initially, Wikidata was a repository of interlanguage links. No Wikipedia language editions were able to access Wikidata, so they needed to continue to maintain their own lists of interlanguage links, on 14 January 2013, the Hungarian Wikipedia became the first to enable the provision of interlanguage links via Wikidata. This functionality was extended to the Hebrew and Italian Wikipedias on 30 January, to the English Wikipedia on 13 February, on 23 September 2013, phase 1 went live on Wikimedia Commons. The first aspects of the second phase were deployed on 4 February 2013, the values were initially limited to two data types, with more data types to follow later. The first new type, string, was deployed on 6 March, the ability of the various language editions of Wikipedia to access data added to Wikidata as part of phase two was rolled out progressively between 27 March and 25 April 2013. On 16 September 2015, Wikidata began allowing so-called arbitrary access, for example, in the past the article about Berlin you could not access data about Germany, but with arbitrary access it could. On 27 April 2016 arbitrary access was activated on Wikimedia Commons, phase 3 will involve database querying and the creation of lists based on data stored on Wikidata. As of October 2016 two tools for querying Wikidata were available, AutoList and PetScan, additionally to a public SPARQL endpoint, there is concern that the project is being influenced by lobbying companies, PR professionals and search engine optimizers. As of December 2015, according to Wikimedia statistics, half of the information in Wikidata is unsourced, another 30% is labeled as having come from Wikipedia, but with no indication as to which article
