Originally compiled by the Office of the Secretary and later by the Academic Appointments Office, this card catalogue contains a record of all appointment letters sent to faculty members beginning in the 1890s. The cards include the appointees' name, degrees, and a record of each appointment (rank, school and academic year). For faculty and officers of research, the last date on the cards is June 30, 1990. For officers of administration, there are cards with information through July 1987. The cards are divided between inactive (last appointment ended before June 1990) and active (still at Columbia in 1990). The active appointments are also subdivided by school or division.
