I agree too, Daff. It's highly irritating when you can't find anything out about a book, even from google, and it surely means these books are very unlikely to swap. Sometimes a title intrigues me and I do take a chance, but even a short description would be a help. I know people say they have no time to put in descriptions, but a few words wouldn't take that long - even a note that the swapper had themselves enjoyed the book.
I also find that sometimes Amazon comes up without a blurb, but if you click 'alternative descriptions' it will sometimes come up with one, or even a choice!
