Abstract

A summary of a survey of the use of the DDC in libraries of the United States and Canada is presented. (5% of alle libraries in the United States and Canada use DDC; of these are at least 75% use the most recent full or abridges edition. Librarians wish to have DDC revised continuously, but they do not want the meanings of numbers changed. Any assistance that can be provided in the application of DDC is welcome. Most of the larger libraries do not believe zhat the current index provides sufficient assistance. Divisions needing revision are listed with an index number reflecting priority. DDC is seen to be warmly regarded by librarians in general and by public service librarians in particular
