The site grew to become the largest glbtq encyclopedia ever created thanks to the work of its editors and more than 350 contributors. The website also included a variety of essays, a few interviews with contemporary figures, and, during its last few years of operation, a blog written by Claude Summers. Claude Summers' blog is archived at the ONE Institute in Los Angeles.
The project also produced three books: The Queer Encyclopedia of the Visual Arts (2004); The Queer Encyclopedia of Music, Dance, and Musical Theater (2004); and The Queer Encyclopedia of Film and Television (2005), all published by Cleis Press.
The website closed on 1 August 2015 because of the collapse of the online advertising business model that had supported it.
Most of the encyclopedia's entries, essays, and interviews have been archived online.
