The problem is that the newbies-- the ones who most need the books(*) -- are fairly unlikely to think of using super search to look for "books-offered". Some sort of visual pointer is needed to give a newcomer the idea that there might be such a thing as a virtual library.

(*) <Hmmm>Isn't this being needlessly patronising to newbies?</Hmmm>

Update epoptai I'm not trying to knock the idea. I think that it's good. Just taking it one step further to make it even more useful :)
