The Jean-Nickolaus Tretter Collection in Gay, Lesbian, Bisexual and Transgender Studies
Welcome
The Jean-Nickolaus Tretter Collection in Gay, Lesbian, Bisexual and Transgender Studies is the largest LGBTQ-specific archival repository in the upper Midwest. It holds approximately 3,500 linear feet of material—including books, periodicals, grey literature, personal and organizational records, zines and pamphlets, artifacts and ephemera, and audiovisual materials. The Collection is national and international in scope (featuring materials in approximately 58 languages), but is especially strong in materials documenting the history of LGBTQ people, organizations, and communities in the Upper Midwest, especially the Twin Cities area. The Tretter also serves as a center for LGBT and queer ideas, hosting panel discussions, community conversations, and other events designed to support critical inquiry into LGBTQ pasts.
