Adding to the Google Bomb. For those who don't know, Amazon has delisted (nearly)* all GLBT books, fictional and non-fictional, from its ranks because it's declared them Adult.
I read the blogs of several agents and publishers, many of whom have already picked this up. I think that's going to be what makes the difference, really; authors whose books have disappeared. Books have been disappearing since February, but there seems to have been a mass pull recently. I'm thinking Amazon has been pulling books in response to complaints for a while, and have decided it'd be quicker to just pull everything tagged Erotica and GLBT, which means they've overlooked things like Playboy books and homophobic manuals that wouldn't use the term GLBT while accidentally picking up kids non-fiction and fairly tame romance novels.
If you're looking for an alternative online bookstore, can I point you towards Better World Books, which sells new and secondhand books, supports literacy charities in the third world, and is even carbon neutral. There's a postage charge outside of the US, but otherwise is does everything bookwise that Amazon does.
