The Library’s holdings consist of several major collections: a book collection, an archival collection, a photo collection, an audio and audiovisual media collection, and a vertical file reference collection.

The book collection contains a number of hard-to-locate and rare items, including cavalry drill manuals, Field Manuals, Technical Manuals, Cavalry School staff studies, unit histories, and many nineteenth century works on equine medicine. The library also boasts a significant collection on related subjects, including general military history and Cavalry-related fiction. The archival collection contains a diverse and varied body of records, including the personal of several twentieth century Army officers and enlisted men who served in the Cavalry, as well as various regimental and Army school records.

The photo collection consists of over five thousand images mostly from the first half of the twentieth century. The Library has digitalized much of its photo collection, which consists of class photos, as well as photos of individuals, military installations, and equipment. The Library also has an extensive collection of equestrian photographs including a significant collection of photos of the equestrian events at the 1932 Los Angeles and 1936 Berlin Olympics.

The vertical file reference collection serves as a ready reference of secondary source material on Cavalry subjects about which the Library receives frequent inquiries.

The Library also maintains a growing Oral History Collection. In cooperation with Texas A&M University, the Cavalry Association is collecting on tape and transcribing the recollections of Cavalry veterans of recent history. Many of these tapes include reminiscences from the Inter war Period, World War II, the Korean War, and the Vietnam Conflict. Transcripts and original audio tapes are available for the many of the interviews already conducted.

The Library also acts as the repository for records created as part of the Cavalry Association’s BIOCAV Program. The BIOCAV Program seeks to create a biographical database of Cavalry veterans from all periods of American history. Veterans of any Cavalry unit are encouraged to complete and submit a biographical data form regarding their Cavalry service. Association members and others with a Cavalry ancestor or relative are also encouraged to complete the form with any supporting documents. The forms are filed together creating an alphabetically organized data bank of particular use to genealogy researchers. Often the files include supporting documents along with the biographical form which are useful to other researchers as well.

At present the Library is cataloging its significant collection of documents and personal papers. As Library completes them, they will add them to this website. We are adding this information to facilitate those researchers and scholars who have specific questions as to the extent of our holdings. The following are the Finding Aides presently available.
