If you've ever downloaded a book from the internet for free chances are it was from Project Gutenberg. They boast over 33,000 FREE titles (and you know how much I like the word free). The e-books are free because the book's copyright has expired. You'll find classics such as:
A Christmas Carol by Charles Dickens
Anne of Green Gables by L. M. Montgomery
Pride and Prejudice by Jane Austen
Robinson Crusoe by Daniel Defoe
The Wonderful Wizard of Oz by L. Frank Baum
Just to name a few.
Most e-readers can use the Project Gutenberg files. Itunes offers them through their iBooks application and Amazon's Kindle has them as well. The books are listed under *FREE* (he, he, imagine that). More info for your specific readers here. But, you can also read the books online from your computer without any special equipment. Just cruise their catalog here and follow the directions for reading online.
Don't know where to start? They have a handy Top 100 books downloaded.
I just downloaded American Frugal Housewife by Lydia Maria Francis Child a homemaking manual from the mid-1800's. I'm just a few pages in and already I'm starting to realize how easy we have it. My household will never take that much work, but I'm finding excellent tips and quotes to use and share.
Plus, a ton of their books are available in audio files for those of us too busy to sit down with a good book.
Well, what are you waiting for? Go download and read a book!
(Nope, no paid advertisement. I just love what they're doing over there.)
