This report presents information for identification of the national trends in the amount, age, loss, condition, and perceived adequacy of academic research equipment in selected science and engineering fields. The data were obtained from a stratified probability sample of 55 colleges and universities and from a separately selected sample of 24 medical schools. Discussions are included on these trends: (1) by type of institution; (2) physical and environmental sciences; (3) engineering, computer science, and materials science; and (4) biological and agricultural sciences. Included are data related to the amount of academic research equipment, fund sources for the equipment, quality of the equipment, patterns of equipment usage, and maintenance and repair of the equipment. Appendices include technical notes, tables, a questionnaire, data sheets, adjustment methodology, sampling errors, and trends in numbers of institutions. (YP)
