This compilation of resources on the United States Air Force Academy includes materials published between 1 January 1983 and 31 December 1989. It updates the third supplement, which was published in 1984. Earlier bibliographies on the Academy include the original, published in 1966, and the first and second supplements, published in 1968 and 1972, respectively. This bibliography does not include articles from local-area newspapers. Reports of specific athletic events are also excluded, regardless of the source. Although recent Academy Assemblies and Harmon Memorial Lectures are a part of this compilation, a number of materials published at the Academy are not included. Finally, a few items are cited which pre-date the years covered by this supplement. These were not listed in previous bibliographies. The basic arrangement is by subject.
