Following up my earlier story about loading fiction onto your smart phone, you should be aware of the wonderful Gutenberg Project. This not-for-profit initiative has compiled electronic versions of over 20,000 books, including virtually any classic you can imagine, and offers them free of charge for download in a number of formats.
The volunteer-staffed project began in 1971, making it the first and longest-lived effort to distribute literature in electronic form. The offerings are either out of copyright or done with the permission of the copyright holder. The books are available in a number of open-source formats including HTML, readable in any browser.
The Gutenberg project has expanded its offerings beyond books, too, now offering audio books, music, sheet music, and video. If you have a hankering for some classic lit and a screen to read it on, the project is ready to hook you up.
