Rapidshared.org lets you access all of the ebooks on the Rapidshare.de fileservers. From their site:
RapidShared.ORG is a catalog of materials, hosted on the servers of rapidshare.de, the world leading file hosting service. Aim of this project is to gather links spread all over the net in one single place and to structurize them in a user-friendly way. All links get checked (if valid, for duplicate entries, etc) to make everything even more comfortable!
I think their servers were overwhelmed the other day, but everything seems to be working now. When I find more ebook links (such as this), I'll always include them on my previous ebooks post.
