This series comprises calendars of classes, raps, workshops, meetings, and other events held by the Center, and of similar events of interest to the gay and lesbian community held by others, as well as flyers, brochures, invitations, correspondence, commemorative booklets, and other materials relating to events sponsored by, or held for the benefit of, the Center. The Center often published several calendars simultaneously, each with a different focus: Center events, community (non-Center) events, women's events, men's events, etc. There is considerable overlap between many of these calendars, and they have therefore been combined and ordered chronologically. Most of the events documented are fundraisers, and range from yard sales to roasts of prominent members of the gay and lesbian community (Sheldon Andelson in 1979 and Gayle Wilson in 1980), annual gala dinners, and to special theatrical performances (Julie Harris in "The Belle of Amherst" in 1976). Other events include Center open houses and art exhibition opening receptions. The events are arranged chronologically. The series does not include records of on-going classes, raps, and workshops, or single presentations held as part of an ongoing series: these records can be found in Subseries 5.15.
