Dewey decimal classification презентация

lack of efficiency, and waste of time and money in constant recataloging and reclassifying made necessary by the almost universally used fixed system where a book was numbered according to the particular room, tier, and shelf where it chanced to stand on that day, instead of by class, division and section to which it belonged yesterday, today and forever. Then there was the extravagant duplication of work in examining a new book for classification and cataloging by each of a 1000 libraries instead of doing this once for all at some central point." - Melvil Dewey, "Decimal Classification Beginnings," Library Journal, 45:151 (Feb. 15, 1920).

and maintained in a national bibliographic agency, the Library of Congress. The Dewey editorial office is located in the Decimal Classification Division of the Library of Congress, where classification specialists annually assign over 110,000 DDC numbers to records for works cataloged by the Library. Having the editorial office within the Decimal Classification Division enables the editors to detect trends in the literature that must be incorporated into the Classification. The editors prepare proposed schedule revisions and expansions, and forward the proposals to the Decimal Classification Editorial Policy Committee (EPC) for review and recommended action.
EPC is a ten-member international board whose main function is to advise the editors and OCLC on matters relating to changes, innovations, and the general development of the Classification. EPC represents the interests of DDC users; its members come from national, public, special, and academic libraries, and from library schools.

and electronic versions. The abridged edition is a logical truncation of the notational and structural hierarchy of the corresponding full edition on which it is based, and is intended for general collections of 20,000 titles or less. WebDewey and Abridged WebDewey, the electronic versions of the full and abridged editions, respectively, are updated frequently and contain additional index entries and mapped vocabulary. The electronic versions and supplemental web postings are the chief sources of ongoing updates to the DDC. On the Dewey web site (www.oclc.org/dewey), selected new numbers and changes to the DDC are posted monthly, and mappings between selected new Library of Congress Subject Headings (LCSH) and Dewey numbers are posted biweekly.
