Where my last 20 reviewed books came from

Marie of The Boston Bibliophile just posted a follow-up to her Bloggers and Commercialism post where she lists the sources of her last 20 reviewed books. She did this to analyze the possible effect not accepting review copies might have on her blog. I found it very interesting for another reason too - it's what Julia Keller calls the "extra story" (how a book found its way to your hands) in her article in the Chicago Tribune yesterday.

So, to both follow in Marie's "full-disclosure" footsteps and to provide you with some "extra stories", here is how I got the last 20 books I reviewed on Presenting Lenore.

I would say this is a pretty typical breakdown, except that normally I'd have more books offered to me via query than books I requested personally. If I stopped accepting "freebies", I probably wouldn't feel the pressure to read as much as therefore I'd be more likely to post one review per week as opposed to three or four as I do now. The types of books I reviewed wouldn't change, since I only request or accept books I'd actually spend money on or check out from the library.

Where did your last 20 reviewed books come from? Do you buy most of your books? Get them from the library? Or if you review mostly free copies, how would your blog change if you stopped accepting them?
