I also post over at BAR and I love to SEE the books that folks are reading. Its an easy thing to do to post the cover of the book you're reading. Just Google the title of your book and hit Images, choose the cover you like best, copy the URL and then come here to post it. To post, click on the little icon that looks like mountains, and put the URL of the book cover in there. That way you don't use up any of your own photo limits.
Here's my latest read.
