Collection contains general and graduate catalogs for Oklahoma A&M College/Oklahoma State University as well as those for summer sessions. No copy issued for 1895, per College Mirror June 15, 1895. During the 1950's separate catalogs were issued for each college or similar academic unit.

Catalogs for departmental offerings, as well as for correspondence studies and for other institutional campuses are housed separately. Some specialized catalogs are located in the OAMC Bulletin Series, which is a separate collection.

Catalogs that are bound are identified. Prefer retaining unbound issues; replace bound ones as the opportunity arises. Retain one copy; however, duplicates of some earlier issues are in the collection as well as acid-free photocopies of early issues. When bound volumes re retained, the reason is indicated. This may be noted by underline below the year(s) missing from the unbound pieces.
