OCLC will sponsor the annual International Dewey Users Meeting in conjunction with the IFLA World Library and Information Congress in Columbus, OH, on Tuesday, 16 August, 8:00–9:30 a.m., Room C124 - C125, Greater Columbus Convention Center. The agenda includes recently approved changes to the Dewey Decimal Classification (DDC), new strategies for identifying potential areas for future development work in the DDC, efforts to link FAST to other controlled vocabularies and Wikipedia and Wikidata, and the principles underlying the European Dewey Users Group (EDUG) recommendations for mapping to Dewey. There will also be demonstrations of ccmapper, a new Dewey mapping product developed by PANSOFT together with the Norwegian Dewey team, and the new user notification feature being developed for WebDewey. Dewey translation partners will share reports. Please register here by 8 August if you plan to attend the meeting.
