lifehacker.com had a good post on finding free Books on Saturday. It was sharing a post from FriedBeef.com, Top 10 Best Places to Get Free Books. The comments to the lifehacker post are as good as either of the actual posts. There are lots of ideas here! DailyLit.com even emails part of a book to you each day.

Note: there are some copyright problem noted on FriedBeef that are interesting to know and consider.
