Kindle

This year Santa brought me a Kindle (well he will when it gets here in early January) but in the meantime I have been looking for book sites that I can use when it arrives.

For those that don't know what a Kindle is it's an e-book reader that is made by Amazon. You can purchase books from Amazon and download them to your Kindle but there are also free book sites that also work with the Kindle. I have selected a few to list here.

1. Project Gutenberg: 33,000 free e-books, including all of the classics, available in Kindle, HTML and simple text formats.
2. Google E-Bookstore: The free section is filled with thousands of free, scanned copies of books, available in Kindle-friendly PDF formats.
3. Internet Archive: Millions of primarily rare, out-of-print works in multiple languages and formats (including Kindle), especially useful for academic work.
4. Open Library: 20 million user-contributed items in multiple editions and formats (including Kindle).
5. ManyBooks.net: Nearly 30,000 titles, many of which have been pulled from Project Gutenberg. Has a good collection of little-known Creative Commons works.
6. LibriVox: Thousands of free audiobooks.

(thanks to Mashable for the list.)

Do you already have a Kindle? If so what do you think of it and what book sites do you use to populate your Kindle with good holiday reading material?
