Quoted: LibraryThing catalogs your books online, easily, quickly and for free.For book lovers, it's a LibraryThing: This site is similar to Del.icio.us, but for the tweed set. If you love books, and love people who love books, LibraryThing is for you. Start by using the service to catalog your book collection: Tag your books by topic, share your catalog with others, and then endlessly browse the titles that they have on their shelves. The utterly book obsessed can add the LibraryThing widget to a blog to show visitors what they have been reading lately. Listing up to 200 books is free; listing any number of books beyond that costs either $10 per year or a one-time $25 fee.

Project Gutenberg is the first and largest single collection of free electronic books, or eBooks. Michael Hart, founder of Project Gutenberg, invented eBooks in 1971 and continues to inspire the creation of eBooks and related technologies today.

The Web's public library, Project Gutenberg offers free e-book versions of public-domain works. A distributed staff of thousands of volunteers transcribe, proofread, convert, and translate the books, which now number over 18,000.

Archiving more than just the Internet (archives are accessible via the "Wayback Machine" on the home page), the Internet Archive also includes tremendous collections of concert recordings, moving images, and much more.
