What is the best website to download books?

I tried to buy books from BarnesAndNoble and Amazon but they said they couldn't or wouldn't make deliveries to Iraq,so my only option is to download.Please tell me which is the best site to go to.

Try any of these websites for purchasing eBooks:

http://www.ebooks.com/

http://www.ebookmall.com/

http://www.booksonboard.com/

Or, here's a website with free eBooks (legal, too):

http://www.gutenberg.org/wiki/Main_Page

For older classic books (published before 1923) start with:

http://www.gutenberg.org

http://manybooks.net

http://www.munseys.com

http://www.webliterature.net

Then do a search for "free e-books" and you will find many more links.

Barnes and Noble and Amazon should be able to deliver to an APO address: http://www.apobox.com/amazon.php
