1001Books.com

One of the awesome Kindle enthusiasts at www.mobileread.com, Daithi, has produced a nice download portal for the Kindle, 1001books.com. At one location, you can browse or search for books that reside, if they are free public domain works, at sites such as mobileread.com and feedbooks.com, and if they are under copyright and for sale, at Amazon.com's Kindle store. If you select a book, the site will:

• Download the book from one of the free sites if it is in the public domain
• Allow one to buy the book from Amazon if it is available but not free
  
• Request Amazon to ask the publishers to make the book available if it isn't available
  

Not only is the site one-stop shopping for these sites, it is particularly nicely designed with a clean, easy-to-navigate look. The site is new, but is already quite useful (and should only get better), has a very nice book list, and saves a lot of hopping around the Web. For more information, the discussion thread on the mobileread forums is here. Definitely check this site out.
