This series contains correspondence, offprints, drafts, notes, journal articles, and newspaper clippings relating to Marmor's research on homosexuality. Marmor's correspondents include longtime lesbian activist Barbara Gittings and researcher Charlotte C. Taylor; his correspondence with Evelyn Hooker, which includes offprints of several of her articles from the 1950s, several handwritten letters from Hooker from the 1990s, and materials relating to her obituary and memorial service in 1996, forms a separate file. Most of the articles and reviews date from the early 1970s, when Marmor was a leader in the movement to remove homosexuality from the American Psychiatric Association's Diagnostic Manual. Several of the articles contain strong rebuttals of the work of Charles W. Socarides and Paul Cameron, in particular. The files include drafts, and photocopies of sources Marmor used. The series also includes a file of several speeches, two sets of handwritten notes by Marmor, and a file of journal and newspaper clippings containing references to Marmor (journal and newspaper articles by and about Marmor are in the "Short Articles and Reviews" folder).
