Abstract
A summary of the report of the Unesco meeting of experts on the problems and strategies of incorporating the social sciences into the world science information system (UNISIST) is given, followed by discussion of the implications for social scientists, as users of information services, of some of the proposals put forward at that meeting. In particular, the problems involved in standardizing terminology for thesauri and other bibliographical facilities, and the advantages which are likely to be derived from common standards of data collection are discussed.
