There's been a discussion on one of my author loops recently about Piers Anthony's site. For those of you who don't know, he posts information regarding ebook publishers and updates the entries (fairly) regularly based on author feedback. I read his site often in my early days of looking for publishers, and though I don't check in that often anymore, every once in a while it's interesting to see what he has to say.
Other authors on my loop, though, have issued MAJOR caveats about his site, claiming that he often posts only one side of an author altercation and can make a publisher sound worse than it actually is. As with anything else on line, folks, it's surfer beware. Take advice with a grain of salt and do your research in more than one place if you can.
Speaking of online sources, though, here's a link to Brenda Hiatt's "Show Me the Money" site, listing romance publishers and their average advances/payouts for authors. Always interesting to peruse (and thanks Wendy for the updated link!)
