According to
World eBook Fair, the "World eBook Fair Collection shelves more than 330,000 PDF eBooks in 100+ languages, [and] contains 90 of the finest eBook collections published on the Internet today."
Much of the content is probably overlap from
Project Gutenberg, and unfortunately they have chosen to present the content in PDF format. But it still looks interesting, and includes an online search index on the main page... "Enter the author's name or the title of the book... You may also search the Full Text content for a 'Word Search'... Over 330,000+ PDF eBooks and eDocuments to choose from."
In addition, it looks like you can also download the entire collection for free starting July 4th. Actually, they may mean that each book in the collection is available for free download, rather than one complete download as offered by
Project Gutenberg downloads. Interestingly, Project Gutenberg may have grown so much that their content may only allow for a "best of" collection even on DVD!
