Hey, does anyone know a site where I can actually find how many pages the book has?

And, what do y'all think of the idea of allowing books on tape? I don't personally see a problem with it, but, wanted to know if y'all think that defeats the purpose of a book club? Just in case there are folks that want to participate, but, maybe can't because of sight problems, time restraints, etc...I don't know...just a thought...
