A lot of those books are not about atheism, they are about science and dismistifying stuff.
Science is different from atheism The Demon-Haunted World for example is just an exposition of science and knowledge, it does not intend to be an atheist book, it doesn't say if there is or not a god, it talks about Known things and not beliefs.
And most of science books also like the selfish gene or the origin of species. They are science books that religious people don't like because they show them to be wrong. But the books per-se are not atheist.
Anyway, is a nice list and some of them that are about atheist are a nice introduction to the philosophy that can make atheism from a "I don't believe because I don't believe, because I don't believe" type of argument(that sounds like theism without a god) to a really "I can explain shit and why gods are inexistent or irrelevant" type of argument.
Thanks for the link, never counted how many books that I had read, but from the looks of the titles I've read quite a few. I have a lot of books, the problem that I had ran into was even though some were very interesting however, some were rather dull and I never finished them, but out of them all they have ended up being repeatative, so I don't read that much any more.
One should be free in there spiritualality to believe what they wish about the universe and our part in it and not be controlled by someone else's perception as long as one is good and honest and straight forward,we do not have to believe another that is our right but need to acknowledge the others point of vieew ,But we definitly do not have the right to act against another or cause harm unless the beliefs and actions of that person effect the whole in a negative way
