10、ents within the world of Dewey Decimal Classification(DDC):developments within the schedule have been matched by those within the process for change,and by ex-pansion in the technical framework that supports the use of DDC.Work on Edition 23 began in March 2004 with a planning retreat to discuss the
11、 direc-tion and aims of Edition 23;the retreat included members of the Decimal Classification Editorial Policy Committee(EPC),the Dewey editors,invited researchers in knowledge organisation from OCLC and elsewhere,and a representative from the DDC translation community.The areas of development in Ed
12、ition 23 include those that were highlighted but could not be incorporated in Edition 22 and those that have emerged during the cycle of production for Edition 23.Edition 23 includes extensive changes and updates in the terminology used throughout the schedules and tables to improve currency and acc
13、essibility for classifiers.There is sig-nificant development of schedule areas impacted by rapidly changing technology over the life cycle of Edition 23 such as computing,and extensive changes to aid interoperability between the different language translations that have been developed during the pro
14、cess of Edition 23.Edition 23 has continued the best practice established during work for earlier editions by seeking expert advice from as wide a community as possible both within and beyond the DDC user base to ensure we continue to represent accurately complex knowledge areas and continue to impr
15、ove the international applicability of the DDC schedules.This new edition is the work of a wide community including the editors,EPC,the European DDC Users Group(EDUG),and colleagues from translation projects.Each has contributed to the proposed areas for review and discussions about new schedules to
16、 ensure accuracy and relevancy for as wide a community as possible.The revision process aims to improve the currency of the schedules,whilst continuing to be sensitive to the use of DDC as a shelving tool.Any major changes inevitably bring challenges to libraries not least the costs of relocating and re-labelling stock.To help alle-viate these problems expansion and revision have been preferred to relocation where pos-sible.Significant changes have only been made after careful thought and debate
