Where to get free Kindle books

Things have changed a lot since I complained in 2007 that Kindles were too expensive, didn't hold enough data, and didn't allow access to pdfs and other books. I adore my Kindle, and am seriously considering getting a second one to take advantage of the great special offers they display as screen savers. I've even read and reviewed so much I'm in the top 1000 Amazon reviewers.

One of the great things about the Kindle is how many free ebooks there are. Here are some places you can get them:

Project Gutenberg and ManyBooks.Net have quite a bit of overlap, but check them out for out-of-copyright books (like all those classics you've meant to read but haven't gotten around to yet).

Books On the Knob and Kindle Review publish the latest and greatest (and often, temporary) deals and steals.

If you're willing to do a little data mining, eReaderIQ will help you find the best price for the title you're looking for.

OverDrive has been making deals left and right with public libraries. Find out if your local library has ebooks available for borrowing (ours does).

Finally, Amazon itself lets you see the 100 most popular free ebooks alongside the 100 most popular ebooks for sale. I check this every once in a while to see what's burning up the charts.
