"Men into Beasts" is a general memoir of the indignities and brutalities of life in prison, but a significant part of it deals with situational homosexuality and male rape in prison. The cover of the book features a discreetly posed nude man, on his knees in a prison cell, being beaten by two prison guards. The text on the back of the book blames prison riots on "homosexual slavery--inmates being forced to practice abnormal acts with sex deviates who roamed the prisons at will." Beginning around 1964, the more than a decade of challenges to U.S. censorship laws applied to literary novels such as "Lady Chatterley's Lover", "Portnoy's Complaint", and "Naked Lunch" had redefined legal standards for obscenity. Susan Stryker cites Tom Norman's bibliography of American gay erotic paperbacks to note that thirty gay paperback books were published in 1965, and that over a hundred were in 1966. Many of these publishers had their roots in publishing beefcake, or "male physique" magazines in the 1950s, precursors to explicit gay pornographic magazines. Most of the new gay paperbacks were explicitly pornographic, writing designed to provoke sexual responses, rather than literary writing, and they came from small, gay presses, such as the Guild Press, Greenleaf Classics, and the Publisher's Export Company, rather than from mainstream national publishers. For example, Greenleaf (under editor Earl Kemp) published a series of erotic spy parodies called "The Man from C.A.M.P.", written by Victor J. Banis. Banis says once Kemp and Greenleaf proved how much of a market there was for this type of fiction, other publishers soon joined in. Among "the more provocative titles and noms de plume" published in this decade include: "Summer in Sodom", by Edwin Fey; "Gay Whore", by Jack Love; "Hollywood Homo", by Michael Starr; "The Short Happy Sex Life of Stud Sorell", by Orlando Paris; "It's a Gay, Gay, Gay, Gay World", by Guy Faulk; "Gay on the Range", by Dick Dale; "Queer Belles", by Percy Queen; and "Gay Pals", by Peter Grande. Sometimes, these past ephemera can become useful community history resources. As Susan Stryker and Michael Meeker note in a new preface to Lou Rand's "The Gay Detective" (1965), San Francisco area LGBT historians found that the paperback in question turned out to be a valuable document in describing past prominent if closeted social figures, ethnic conflicts over police corruption and the emergence of a narcotics underworld in their city, as well as referring to bygone LGBT venues.
