Online Public Access Catalog
The online public access catalog (OPAC), now frequently synonymous with ''library catalog'', is an online database of materials held by a library or group of libraries. Online catalogs have largely replaced the analog card catalogs previously used in libraries. History Early online Although a handful of experimental systems existed as early as the 1960s, the first large-scale online catalogs were developed at Ohio State University in 1975 and the Dallas Public Library in 1978. These and other early online catalog systems tended to closely reflect the card catalogs that they were intended to replace. Using a dedicated terminal or telnet client, users could search a handful of pre-coordinate indexes and browse the resulting display in much the same way they had previously navigated the card catalog. Throughout the 1980s, the number and sophistication of online catalogs grew. The first commercial systems appeared, and would by the end of the decade largely replace system ...

Library Catalog
A library catalog (or library catalogue in British English) is a register of all bibliography, bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A catalog for a group of libraries is also called a union catalog. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia (library science), realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library. The earliest library catalogs were lists, handwritten or enscribed on clay tablets and later scrolls of parchment or paper. As codex, codices (books with pages) replaced scrolls, so too did library catalogs become like handwritten ledgers and, in some cases, printed books. During the late 18th century ...

Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

ERIC
The given name Eric, Erich, Erikk, Erik, Erick, Eirik, or Eiríkur is derived from the Old Norse name ''Eiríkr'' (or ''Eríkr'' in Old East Norse due to monophthongization). The first element, ''ei-'' may be derived from the older Proto-Norse ''* aina(z)'', meaning "one, alone, unique", ''as in the form'' ''Æ∆inrikr'' explicitly, but it could also be from ''* aiwa(z)'' "everlasting, eternity", as in the Gothic form '' Euric''. The second element ''- ríkr'' stems either from Proto-Germanic ''* ríks'' "king, ruler" (cf. Gothic '' reiks'') or the therefrom derived ''* ríkijaz'' "kingly, powerful, rich, prince"; from the common Proto-Indo-European root * h₃rḗǵs. The name is thus usually taken to mean "sole ruler, autocrat" or "eternal ruler, ever powerful". ''Eric'' used in the sense of a proper noun meaning "one ruler" may be the origin of '' Eriksgata'', and if so it would have meant "one ruler's journey". The tour was the medieval Swedish king's journey, when new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medline
MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online) is a bibliographic database of life sciences and biomedical information. It includes bibliographic information for articles from academic journals covering medicine, nursing, pharmacy, dentistry, veterinary medicine, and health care.

History MEDLARS (Medical Literature Analysis and Retrieval System) was a computerised biomedical bibliographic retrieval system. It was launched by the National Library of Medicine in 1964 and was the first large-scale, computer-based, retrospective search service available to the general public. Initial development of MEDLARS Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibliographic Database
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like academic journal, journal and newspaper articles, conference proceedings, reports, government and legal publications, patents and books. In contrast to library catalogue entries, a majority of the records in bibliographic databases describe articles and conference papers rather than complete monographs, and they generally contain very rich subject descriptions in the form of Index term, keywords, subject classification terms, or abstract (summary), abstracts. A bibliographic database may cover a wide range of topics or one academic discipline, academic field like computer science. A significant number of bibliographic databases are marketed under a trade name by licensing agreement from vendors, or directly from their makers: the indexing and abstracting services. Many bibliographic databases have evolved into digital library, digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

WorldCat
WorldCat is a union catalog that itemizes the collections of tens of thousands of institutions (mostly libraries), in many countries, that are current or past members of the OCLC global cooperative. It is operated by OCLC, Inc. Many of the OCLC member libraries collectively maintain WorldCat's database, the world's largest bibliographic database. The database includes other information sources in addition to member library collections. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscription OCLC services (such as resource sharing and collection management). WorldCat is used by librarians for cataloging and research and by the general public. , WorldCat contained over 540 million bibliographic records in 483 languages, representing over 3 billion physical and digital library assets, and the WorldCat persons dataset ( mined from WorldCat) included over 100 million people.

Interlibrary Loan
Inter-library loan (abbreviated ILL, sometimes called document delivery, document supply, inter-lending, inter-library services, inter-loan, or resource sharing) is a service that enables patrons of one library to borrow materials that are held by another library. Methods After receiving a request, the borrowing library identifies potential lending libraries with the desired item. The lending library delivers the item physically or electronically, and the borrowing library receives the item and delivers it to their patron, and if necessary, arranges for its return. Sometimes, fees accompany interlibrary loan services. Libraries can define what materials from their holdings are eligible for interlibrary loan. Many journal or database licenses specify whether a library can or cannot supply journal articles via ILL, with libraries negotiating for ILL eligibility. The International Organization for Standardization (ISO) developed ISO standards ISO 10160, 10160 and ISO 10161, 10161 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Catalog
A union catalog is a combined library catalog describing the collections of a number of libraries. Union catalogs have been created in a range of media, including book format, microform, cards and more recently, networked electronic databases. Print union catalogs are typically arranged by title, author or subject (often employing a controlled vocabulary); electronic versions typically support keyword and Boolean queries. Union catalogs are useful to librarians, as they assist in locating and requesting materials from other libraries through interlibrary loan service. They also allow researchers to search through collections to which they would not otherwise have access, such as manuscript collections. The largest union catalog ever printed is the American '' National Union Catalog Pre-1956 Imprints'' (NUC), completed in 1981. This achievement has since been superseded by the creation of union catalogs in the form of electronic databases, of which the largest is OCLC's WorldCat.Wa ...
