This subseries consists of materials pertaining to educational programming and research initiatives completed by Gay People at Columbia-Barnard (GPCB) and Columbia Gay and Lesbian Alliance (CGLA). The subseries is organized by educational event type, with folder contents organized chronologically. The first files consist of fliers, handouts, syllabi and readings for discussion groups organized by GPCB and CGLA, specifically consciousness raising groups in the 1970s and study groups in the 1980s. Some of the readings are annotated. Following the discussion group materials are memos, fliers, discussion plans, and reports for GPCB's "floor raps," in which GPCB members would lead an information session about homosexuality to residents of a dormitory floor. The memos consist of internal communications reflecting on the success of particular events as well as communications with residence staff. The following files consist of two 1973 and 1974 research initiatives, two separate blank surveys and subsequent reports about sexual experience and gay life at Columbia University. The series concludes with fliers for miscellaneous educational panels, including completed questionnaires for panels on "Coming Out" and "Gays in Business," as well as collected lecture notes, syllabi, and a proposed essay prize pertaining to gay studies at the university.

This subseries consists of materials pertaining to social activities organized by Gay People at Columbia-Barnard (GPCB) and Columbia Gay and Lesbian Alliance (CGLA), divided into three categories: the gay lounge, film screenings, and miscellaneous social activities. The subseries largely consists of internal memos, correspondence, clippings, and press statements pertaining to GPCB's nationally reported struggle to achieve official administrative recognition for the gay lounge, ca. 1971-1973. This collection of materials includes communications with university deans and trustees as well as minutes from a meeting of the Board of Trustees in which GPCB member Morty Manford asked the board for assistance in receiving administrative recognition. The subseries also includes correspondence and fliers related to film screenings either organized by or receiving support from GPCB, including a handout for a post-film discussion of Boys in the Band (1970), a drama about a group of gay friends in New York City controversial for its arguable reproduction of harmful stereotypes. Invited to participate in the screening by its organizers, GPCB planned a discussion that aimed to foster a more critical take on a film the group wouldn't have personally chosen to screen due to ideological reservations. The end of the subseries consists of promotional fliers for miscellaneous social events organized by the GPCB as well as a folder of undated photos labeled "Author's Night at Lounge."
