The Library of Congress Classification 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, including Taiwan, ROC. Most public libraries and small academic libraries continue to use the older Dewey Decimal Classification. Indeed, the Taipei public library in ROC uses Dewey for English-language books. LCC should not be confused with LCCN, the system of Library of Congress Control Numbers assigned to all books, which also defines URLs of their online catalog entries, such as "82006074" and "http://lccn.loc.gov/82006074". The Classification is also distinct from Library of Congress Subject Headings, the system of labels such as "Boarding schools" and "Boarding schools—Fiction" that describe contents systematically. Finally, the classifications may be distinguished from the call numbers assigned to particular copies of books in the collection, such as "PZ7.J684 Wj 1982 FT MEADE Copy 1" where the classification is "PZ7.J684 Wj 1982". The classification was invented by Herbert Putnam in 1897, just before he assumed the librarianship of Congress. With advice from Charles Ammi Cutter, it was influenced by his Cutter Expansive Classification and by the DDC, Dewey. It was designed specifically for the purposes and collection of the Library of Congress to replace the fixed location system developed by Thomas Jefferson. By the time Putnam departed from his post in 1939, all the classes except K and parts of B were well developed. Wikipedia [ - ]
