The Transgender Foundation of America’s (TFA) archive of transgender history and research library is the beating heart of the transgender center located in Houston, Texas. For far too long, transgenders lived without a sense of history as a people. The Houston Transgender Archive addresses this by actively searching out and acquiring transgender history. The TFA research library includes journals, studies, biographies and more, both current and obscure. The library includes both the most current information on transgender issues as well as delicate books that are hundreds of years old.
Currently, the archive holds transgender magazines dating back to 1750, transgender statuary from diverse cultures such a China, Africa and Europe, original newspapers recording transgender history dating back to the early 1700s, rare transgender books dating back to the 1600s, original transgender photos dating back to before the Civil War and other transgender artifacts dating back as far as the Roman Empire.
