I realize this post is three months late, but I would like to clear up a few points about Alyson Books, in case anyone is still trying to submit material.
Alyson was moved entirely to New York City in 2005, shortly before PlanetOut's acquisition of LPI Media, which is perhaps best known for the national LGBT magazines The Advocate and Out as well as several gay men's erotic publications. Before the move, Alyson's Los Angeles staff was totally replaced. Until recently, LPI also had an agreement with Bruno Gmünder and a few other presses to put out photo books and other erotic titles in addition to any released by Alyson. For a brief time, Alyson also had an Advocate Books imprint.
All that is now a thing of the past, now that a nearly bankrupt PlanetOut finalized the sale in August of LPI (Alyson and all the magazines, including all the erotic titles) to Regent Entertainment, which owns the here! network.
I can't tell you much about Alyson now, other than that it has a tiny in-house staff, a few off-site freelancers, and is still based in New York for now at Regent's behest. Before the sale to Regent, the business model for Alyson was already moving away from fiction, gay social issues, and even erotica in favor of things like college guides and travel guides for LGBT readers, self-help manuals, and fluffy Queer Eye–type stuff like dating or fashion do's and don'ts and humorous tales about gay people and their beloved pets. I can only imagine that at this point things have moved farther in that direction.
