Over 250 microcomputer software packages, intended for use on MS-DOS machines by scholars and teachers in the humanities and social sciences, are included in this catalog. The clearinghouse's first Macintosh listing is included, with many more Macintosh programs and data sets being planned and tested for future inclusion. Most programs were written by scholars and instructors with the special needs of academic research or computer-assisted instruction in mind. The software listings are divided as to subject: anthropology, Apple II Humanities Library, Apple II Social Science Library, Apple II Statistics Library, art and graphics, data sets, economics and business, education and authoring systems, English, foreign language, geography and mapping, general interest, history, management programs, philosophy and religion, political science, psychology, research methodology and surveys, sociology, and statistical packages and expert systems. Short annotations are given for each product and a price list is included. Sample screens are illustrated for some programs. Appendices have sample peer review boards interest, literature distribution, and order forms; and a product index. (JB)
