The library is credited for this list of books.

Quatrefoil Library in St. Paul is one of the few GLBT lending libraries in the country. It’s a small operation with limited hours, but it has been an important resource for the entire community. The mission of Quatrefoil is to promote understanding of GLBTQ issues and culture and foster an appreciation of diversity and history and the value of communities. Their collection includes thousands of books, DVDs, audiotapes, newsletters and periodicals reflecting GLBT and Queer experiences.
