* Library classification

From Wikipedia, the free encyclopedia

"A library classification is a system of coding and organizing library materials (books, serials, audiovisual materials, computer files, maps, manuscripts, realia) according to their subject and allocating a call number to that information resource. Similar to classification systems used in biology, bibliographic classification systems group entities together that are similar, typically arranged in a hierarchical tree structure. A different kind of classification system, called a faceted classification system, is also widely used which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in multiple ways." ...

* Dewey Decimal Classification
From Wikipedia, the free encyclopedia

"The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876; it has been greatly modified and expanded through 22 major revisions, the most recent in 2003.^[1] This system organizes books on library shelves in a specific and repeatable order that makes it easy to find any book and return it to its proper place. The system is used in 200,000 libraries in at least 135 countries.^"...

Library of Congress Classification
From Wikipedia, the free encyclopedia


"The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries. It is not to be confused with the Library of Congress Subject Headings or Library of Congress Control Number. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC)."

"The classification was originally developed by Herbert Putnam in 1897, just before he assumed the librarianship of Congress. With advice from Charles Ammi Cutter, it was influenced by Cutter Expansive Classification, and the DDC, and was specially designed for the special purposes of the Library of Congress."

"The new system replaced a fixed location system developed by Thomas Jefferson. By the time of Putnam's departure from his post in 1939, all the classes except K (Law) and parts of B (Philosophy and Religion) were well developed. It has been criticized as lacking a sound theoretical basis; many of the classification decisions were driven by the particular practical needs of that library, rather than epistemological considerations."

"Although it divides subjects into broad categories, it is essentially enumerative in nature. It provides a guide to the books actually in the library, not a classification of the world."
