The series of Beta Alpha Psi membership cards fills two boxes and spans the years 1921-1980. During 1980, the 3″ × 5″ cards were replaced by data forms used to create a computer data base of all members. A sample data form is in the series. The membership cards lists information about the member including: name, college address, permanent address, chapter initiated by (Gamma at Northwestern University), date of initiation, date of graduation, chapter president's signature, employers' addresses, dates employed, positions held, advanced degrees, CPA status, and whether the member was faculty, honorary, or active.
The addition to the Beta Alpha Psi fraternity (Gamma Chapter) records consists of one volume of membership records. These records contain information relating to the member's address, high school attended, colleges attended, and membership in other clubs and associations. The records are contained in the volume in reverse chronological order, from 1934 to 1921.
