The topic looks lonely. I thought I would report that I just finished a three day stint of selling used books for charity....I looked as I always do for something by Barbara Paul, but I didn't see it. (I didn't have a chance to look at ALL the thousands of books we had, but I covered the fiction pretty well)
I hope that means that people who own Barbara Paul keep Barbara Paul!
Incidentally, it could have been lurking somewhere else, because I found copies of "The Picture of Dorian Gray" scattered in with Religion, Psychology, Children's and a couple of other topics......Indeed there were so many copies of it I decided it must have been required reading in some class and everybody was dumping their copies.
