ALL EDITIONS OFDDC The first edition was issued without Dewey’s name, but having the “copyright”, in 1876, in Amherst, Massachusetts: “A Classification and 43 Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library” having 42 pages: introduction (12 pages), the scheme of 1000 index terms (12 pages) and an index (18 pages), in a number of 1000 copies. The second, “revised and greatly enlarged” edition was published under Dewey’s name in 1885. Since that time 20 more full editions and 14 abridgments have appeared. The fourteenth edition, published in 1942, remained the standard edition for many years because an experimental index to the fifteenth edition, published in 1951, was unsuccessful.
- 12. DDC 23rd –LATEST EDITION Edition 23 is the product of a new approach to development of print editions of the Dewey Decimal Classification. Like its predecessor Edition 22, it was prepared in the context of the web, but Edition 23 is the first to be produced as a by-product of the underlying database instead of as the sole focus of editorial development. Editorial development efforts since the publication of Edition 22 have focused on short- term and long-term updates. overall goal of keeping pace with knowledge, changes have been motivated by classifier efficiency and emerging requirements in machine representation and application. Our efforts have been informed by interaction with the worldwide community of Dewey users Edition 23 features a complete overhaul of the representation of groups of people, significant revisions to several standard subdivisions, numerous updates throughout the tables and schedules, and some structural changes. During the production cycle for Edition 23, we have migrated to a new editorial support system, adopted a different underlying data format, and introduced a new data distribution model.
