I've had people ask me for a free book several times, which always surprises the heck out of me. I mean, if my publisher doesn't sell X amount of copies, I'm out of a job. You wouldn't ask an actor for a free DVD of the movie they just filmed, but for some reason certain people think books are different and if you've just written one, you must have oodles of freebies ready to hand out. Even some close friends expected free copies.

I'm starting to get more and more requests from publicists via my blog; my policy is that I post about books I've personally read and liked. I don't do giveways or contests via the blog, but I did recently accept a book for review from the publicist of an author whose work I've read in the past and loved. That's probably my sole exception. I want people to trust that I'm blogging about books I enjoyed and stand by; my taste is quite varied, so I figure there'll eventually be something for everyone. Plus, as I review for the Historical Novel Society, I get ARCs and these I donate to a local retirement home. I think ARCs should be used strictly for review, as intended. Whenever I see one being sold in a used bookshop - and I do more often than I like - I flip out a little, as neither the publisher nor the author will see a dime from that sale.
Still, I think a limited number of contests / giveaways are great, especially as a book launches and the author can benefit from that extra publicity.
