CLASSIFICATION RESEARCH GROUP BULLETIN No. 4

The Classification Research Group is an independent group which was formed in 1952 (ref. 1) and meets in London at approximately monthly intervals. It has published one general memorandum (ref. 2), a bibliography of papers by its members (ref. 3), and three duplicated Bulletins (now out of print). In future, by courtesy of Aslib and the Editorial Board of the Journal of Documentation, its bulletin will be published as part of this journal.
