I'm a new member, and listed Harlan Coben's "The Innocent" in paperback.  My copy is the same as the one shown in the Amazon link, but somehow doesn't match the ISBN number of the 2 requests from members.  Is there any way to bring my book to the attention of the people looking for it?

Patricia.  RIGHT HERE.  I offer Deals or even simply do a post that says I have THESE books in particular on my shelf.  Come have a look. 

Advertising in the Book Bazaar is a good way, there is a thread dedicated to just that. This wishers also get an email from the site when a similar book has been posted.

Since the WL books are only audio and HC and there are over 300 copies of your paperback version already in the system, my guess is that those wishers want only those versions.
