Yes, I'm talking about publishing imprints Amazon is launching in their original publishing programs. They have a romance imprint (can't recall the name), a mystery and thriller imprint (Thomas and Mercer), and I think others. I believe the first books are due out next month, but I'm not sure about that. Larry Kirshbaum, highly respected in publishing circles, is on board in NY, but the imprints themselves are being run out of Seattle, where Amazon is headquartered. Barry Eisler signed with them, and Lee Goldberg. (They're also doing another author's backlist for at least one series through an imprint I believe is called Encore.) They're beginning to attract some fairly well-known writers who have solid publishing histories with the Big 6 in New York.
I'm told their contracts are the most author-friendly ever seen in the business by at least one very experienced and savvy author.
It's clear Amazon wants to be a major player in publishing, and they certainly can be with ebooks. What remains to be seen, I think, is whether they have the distribution channels and clout to get their paper-published books out there just as aggressively.
