40,000 Free eBooks and eTexts for Your Mobile Devices (iPad, iPhone, Kindle, Samsung Galaxy, etc.
You can read books and novels on your book readers. Of course, it's easier to read a paper book, but book readers have their advantages: you can carry twenty or thirty novels in your book reader, it always remembers what page you were at, and you can read anytime, anywhere.
There are perhaps 200,000 etexts on the net: books, documents, maps, etc. Some of the following collections have links to more collections.
Don't ignore ASCII format. It has been around for thirty years, and it's certain that we will use ASCII twenty years from now, whereas it's also certain that whatever book reader format we use today, it will be obsolete in a few years. So if you're creating a worthwhile document, save it in both PDA and ASCII format, and make it available in both.
The following are in no particular order. If you find a broken link, please let me know by adding a comment below.
