FYI, if you want to help bring these old works – specifically books – into the public digital domain, you can volunteer with Project Gutenberg which takes scans of out-of-copyright books as has hordes of volunteers type them up and check them over to turn them I to freely available e-books. It's fun, easy, and covered loads of languages and genres.
Edit: I misused the phrase "type up" and it seems to be annoying lots of people. They use OCR on scanned images of the book, then volunteers check that it has not made mistakes, proofread and edit the text for eBook format.
