Speaking of books…
Project Gutenberg has been collecting a healthy database of digital books for something like 30 years now. Tonnes of free books, searchable and downloadable; now they have an RSS feed for updates.
If you’ve exhausted the already 20,000 full catalog, now you can keep track of new additions through this feed.
