The Bliss bibliographic classification (BC) is a library classification system that was created by Henry E. Bliss (1870–1955) and published in four volumes between 1940 and 1953. Although originally devised in the United States, it was more commonly adopted by British libraries. A second edition of the system (BC2) has been in ongoing development in Britain since 1977.
The Cutter Expansive Classification system is a library classification system devised by Charles Ammi Cutter. The system was the basis for the top categories of the Library of Congress Classification.
The Dewey Decimal Classification (DDC), colloquially known as the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. It was first published in the United States by Melvil Dewey in 1876. Originally described in a 44-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers.
The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress in the United States, which can be used for shelving books in a library. LCC is mainly used by large research and academic libraries, while most public libraries and small academic libraries use the Dewey Decimal Classification system. The classification was developed by James Hanson, with assistance from Charles Martel, in 1897, while they were working at the Library of Congress. It was designed specifically for the purposes and collection of the Library of Congress to replace the fixed location system developed by Thomas Jefferson.
A library classification is a system used within a library to organize materials, including books, sound and video recordings, electronic materials, etc., both on shelves and in catalogs and indexes. Each item is typically assigned a call number, which identifies the location of the item within the system. Materials can be arrange by many different factors, typically in either a hierarchical tree structure based on the subject or using a faceted classification system, which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in many ways.
The Universal Decimal Classification (UDC) is a bibliographic and library classification representing the systematic arrangement of all branches of human knowledge organized as a coherent system in which knowledge fields are related and inter-linked. The UDC is an analytico-synthetic and faceted classification system featuring detailed vocabulary and syntax that enables powerful content indexing and information retrieval in large collections. Since 1991, the UDC has been owned and managed by the UDC Consortium, a non-profit international association of publishers with headquarters in The Hague, Netherlands.
A faceted classification is a classification scheme used in organizing knowledge into a systematic order. A faceted classification uses semantic categories, either general or subject-specific, that are combined to create the full classification entry. Many library classification systems use a combination of a fixed, enumerative taxonomy of concepts with subordinate facets that further refine the topic.
The Nippon Decimal Classification is a system of library classification developed for mainly Japanese-language books maintained and revised by the Japan Library Association since 1948. Originally developed in 1929 by Kiyoshi Mori, the 10th and latest edition of this system was published in 2014. The decimal notation system is similar to the Dewey Decimal System, and the order of main classes is inspired from the Cutter Expansive Classification. The system is based upon using a three digit number to classify subjects, where more digits can be added if necessary and a decimal point is used to separate the third and fourth digit. The first division level is called a class, the second level is called a division, and the third level is called a section. Each '1-9' digit is used to represent a specific category, with the digit '0' being used to represent general works.
The National Library of Medicine (NLM) classification system is a library indexing system covering the fields of medicine and preclinical basic sciences. The NLM classification is patterned after the Library of Congress (LC) Classification system: alphabetical letters denote broad subject categories which are subdivided by numbers. For example, QW 279 would indicate a book on an aspect of microbiology or immunology.
Minnesota's 6th congressional district includes most or all of Benton, Carver, Sherburne, Stearns, Wright, and Anoka counties. Many of the Twin Cities' outer northern and western suburbs are included within the boundaries of this district, such as Blaine, Andover, Chaska, Ramsey, St. Michael-Albertville, Elk River, Chanhassen, Otsego, Lino Lakes, Buffalo, Ham Lake, Monticello, Waconia, Big Lake, East Bethel, and Victoria. The St. Cloud Area is the other major center of population for the district, including the cities of St. Cloud, Sartell, Sauk Rapids and Waite Park.
The Korean Decimal Classification (KDC) is a system of library classification used in South Korea.
Knowledge organization (KO), organization of knowledge, organization of information, or information organization is an intellectual discipline concerned with activities such as document description, indexing, and classification that serve to provide systems of representation and order for knowledge and information objects. According to The Organization of Information by Joudrey and Taylor, information organization:
examines the activities carried out and tools used by people who work in places that accumulate information resources for the use of humankind, both immediately and for posterity. It discusses the processes that are in place to make resources findable, whether someone is searching for a single known item or is browsing through hundreds of resources just hoping to discover something useful. Information organization supports a myriad of information-seeking scenarios.
In library and information science documents are classified and searched by subject – as well as by other attributes such as author, genre and document type. This makes "subject" a fundamental term in this field. Library and information specialists assign subject labels to documents to make them findable. There are many ways to do this and in general there is not always consensus about which subject should be assigned to a given document. To optimize subject indexing and searching, we need to have a deeper understanding of what a subject is. The question: "what is to be understood by the statement 'document A belongs to subject category X'?" has been debated in the field for more than 100 years
Dewey-free refers to library classification schemes developed as alternatives to Dewey Decimal Classification (DDC). Dewey-free systems are often based on the BISAC subject headings developed by the Book Industry Study Group, and are typically implemented in libraries with smaller collections. Instead of using numerical notation to indicate a document's shelving location, Dewey-free systems organize documents alphabetically by natural language words. Dewey-free systems have been implemented in both public and school libraries.
Jennie Dorcas Fellows, also known as Dorcas Fellows and Dorkas Fellows, was an author and instructor of library cataloging at the New York State Library. Her book, Cataloging Rules, originally published in 1914 as bulletin 36 of the New York State Library School, remains in print in its many editions and formats.
The British National Bibliography (BNB) was established at the British Museum in 1949 to publish a list of the books, journals and serials that are published in the United Kingdom and Republic of Ireland. It also includes information on forthcoming titles. This is the single most comprehensive listing of UK titles. UK and Irish publishers are obliged by legal deposit to send a copy of all new publications, including serial titles, to the BNB for listing. The BNB publishes the list weekly in electronic form: the last printed weekly list appeared in December 2011.
The Information Coding Classification (ICC) is a classification system covering almost all extant 6500 knowledge fields. Its conceptualization goes beyond the scope of the well known library classification systems, such as Dewey Decimal Classification (DDC), Universal Decimal Classification (UDC), and Library of Congress Classification (LCC), by extending also to knowledge systems that so far have not afforded to classify literature. ICC actually presents a flexible universal ordering system for both literature and other kinds of information, set out as knowledge fields. From a methodological point of view, ICC differs from the above-mentioned systems along the following three lines:
- Its main classes are not based on disciplines but on nine live stages of development, so-called ontical levels.
- It breaks them roughly down into hierarchical steps by further nine categories which makes decimal number coding possible.
- The contents of a knowledge field is earmarked via a digital position scheme, which makes the first hierarchical step refer to the nine ontical levels, and the second hierarchical step refer to nine functionally ordered form categories.
Evelyn May Seymour was an American librarian who collaborated closely with Melvil Dewey on the Dewey Decimal Classification (DDC). Seymour edited eight editions of the DDC.
Superintendent of Documents Classification, commonly called as SuDocs or SuDoc, is a system of library classification developed and maintained by the United States Government Publishing Office. Unlike Library of Congress Classification, Dewey Decimal Classification, or Universal Decimal Classification, SuDocs is not a universal system. Rather, it is intended for use only with publications of the Federal Government of the United States. Also, SuDocs does not organize materials by subject, but by the agency that created those materials, making it a provenance-based or archival classification system.
