With its archives, GPU donated its library to the UWM Libraries. The library consisted of
books, magazines, and newspapers assembled by the GPU Library Committee, which was chaired
by Eldon Murray. According to GPU's 1974 annual report, the collection amounted to
approximately 1,500 volumes and was "probably the largest library collection about
homosexuality in the state." The committee developed the library largely from items
purchased with GPU funds, donated by individuals, and received as review and exchange
copies. The collection was stored in Eldon Murray's home from the early 1980s until its
acquisition by the UWM Libraries in 2007. The catalog records of titles acquired by Special
Collections include the following note: "From the collection of Eldon Murray/Gay Peoples
Union." Other titles were added to the general holdings of the UWM Libraries or donated to
SAGE/Milwaukee for addition to its own library.
