Two books on gay and lesbian history:
Out of the Past: Gay and Lesbian History from 1869 to the Present, by Neil Miller (TPB, 1995, 657 pages, $3.50)
Hidden from History: Reclaiming the Gay and Lesbian Past, edited by Martin Duberman (TPB, 1990, 579 pages, $3.50)
Of the two, the later one covers the most ground. There we have descriptions of "gay and lesbian life as it evolved in places as diverse as the Athens of Plato, Renaissance Italy, Victorian London, Jazz Age Harlem, Revolutionary Russia, Nazi Germany, Castro's Cuba, post WWII San Francisco- and peoples as varied as South African black miners, American Indians, Chinese courtiers, Japanese samurai, English schoolboys and girls, and urban working women."
