Full text links to the entire series of Carlos Castenada books! Yes, you can find them all on Scribd.com or elsewhere yourself, but I've done the hard work here for you.
So why not save paper? Instead of buying each of these books separately, get yourself a nice cheap PocketPC on eBay for the same price or less and read them all on screen? I did. And it was SO worth it. Just think of how many more books you can find online these days. (They also make an excellent writing tool.)
My Tips for PocketPCs:
1. Get one with a thumb scroll wheel for easy one-hand reading. Seriously.
2. No it doesn't hurt your eyes, just turn the brightness setting way down alright?
It's even better than reading by a bedside lamp.
3. Do not bother trying to read PDFs. Despite being pushed as an eBook format, they are slow and hard to display on small devices. Get the text or document form of what you're reading or convert it on your PC first.
