I'm writing a paper for a history class on rural gay men in America during the latter half of the 20th century. It's not super ironed out yet, as the topic will change based on the primary sources I can find -- but so far I can't find any! I've got plenty of secondary sources but even looking through their footnotes has yielded no results. Does anyone know where I could find open-source primary sources relating to this topic?
