I just picked up Ansel Adams' "Examples: the making of 40 photographs", where he picked out 40 of his images and described what was going through his mind at the time he made the image, as well as his photographic style and some technical info. I haven't actually read it yet, but it looks like it will be a good one.
I also picked up "The Photographer's Eye" as well and I'm looking forward to that read, as well.
Another thing I've been doing lately is looking at other people's images more closely and figuring out what I like about them so I can incorporate elements of their own style into mine.
A couple more books that are on my "to buy" list include:
Amazon.com: Ansel Adams: 400 Photographs: Ansel Adams, Andrea G. Stillman: Books Amazon.com: The Life of a Photograph: Sam Abell: Books (this one doesn't come out until October)
