It looks as though Library Journal is going to start posting a 'most borrowed' list. I think this is a really good idea though try as I might, I went around their website and couldn't find it. I did end up finding something extremely cool/helpful: PrePub Alert. Now I can see a list of all (or most) upcoming releases. They also have bestseller lists at LJ but I always use Booksense's Bestseller List, because it's based on the sales in independant bookstores.
