In a teleconference on "Integrated Databases for Higher Education" held in March, 1975, conference participants identified a number of data bases that could be potential data sources for the larger higher education community. This document is a listing of those data bases together with others that have been subsequently identified. Criteria for inclusion in this catalog were the following: (1) the data base must be reasonably available to other potential users; (2) the data base must be relevant to the postsecondary education community; (3) the data base must be recent; and (4) the data base must identify no specific individuals. Entries are described in general terms with emphasis on the content rather than the form of the data from a technical, data processing point of view. (DGC)
