Collection documents LGBTQ+ communities, organizations, activism, oppression, history, cultural events, trends, and erotica. The collection primarily consists of published materials from Canada and the United States, but also contains resources collected as a result of Aveline’s travels around the world. Collection illustrates changing perspectives on homosexuality and homosexual identity and acceptance, with a strong focus on the period from 1960 to 2009. Collection has a particular focus on documenting the AIDS crisis, LGBTQ+ liberation, anti-gay perspectives, sexuality and eroticism, religion, and Pride events.

Collection is divided into six series: S1 – Public health; S2 – Religious viewpoints; S3 – Erotica; S4 – Lifestyle; S5 – Political action and anti-oppression; S6 – Historical and Aveline Research. The collection is primarily made up of publications such as pamphlets, newsletters, magazines, newspapers, academic journal articles, books, and catalogues. However, the collection also includes other ephemera such as posters, matchbooks, buttons, tourist maps, guides, correspondence, recorded radio programs, postcards, surveys, and teaching materials.
