The purpose of this study was to determine the adequacy of base library service and collections to support the undergraduate and graduate study programs undertaken on United States Air Force installations by officers and airmen, through civilian institutions, during off-duty hours. Basic to the study was the development of a method of library evaluation that would be applicable to the individual base libraries concerned with supporting specific academic programs, yet at the same time have the broad applicability necessary to establish it as a rating system for any Air Force base library engaged in supporting such programs. The evaluation system developed consisted of a formula of point scales to be used in rating the resource and service elements of the base libraries. With a few notable exceptions Air Force base libraries were found to be generally inadequate in their capacity to support off-duty education programs of undergraduate and graduate level. Inadequate communication between base librarians and representatives of the educational institutions, existing personnel authorizations, and levels of expenditures for library materials, were reasons for the lack of curriculum-related library resources. Recommendations for improvement were made as a result of the study. (Author/RM)
