Free books and textbooks for homeschoolers.

Here are three great sites for free books:

Project Gutenberg is the first producer of free ebooks. Hundreds of books in their collection.

Global Text Project will create open content electronic textbooks that will be freely available from a website. Distribution will also be possible via paper, CD, or DVD.

Flat World Knowledge is a work in progress. The goal is to provide free college textbooks to all.
