Project Gutenberg is a great site, dedicated to recording and providing access to knowledge in the form of ebooks, audiobooks etc.

Today I found 'Meditations' by Marcus Aurelius, a book on primitive shelters, huts and log cabins and an Anglo-Saxon dictionary, all for free. It's all old stuff, but there is a great deal of knowledge to be found.
