I have Every Which Way But Dead by Kim Harrison.Its shows one copy up with no WL's but the other book that looks the same cover has 24 wishers.Is it a different type of PB or can I post it to the one that has 24 wishers?Do they realize that there are other PB Types?

You cannot post a book to an ISBN that does not match. Even though your version may not have any wishers, people do check for other versions and it will probably be claimed quickly. 

You have to post it using the ISBN found on the copy you have.  If your copy is the one without any wishers, you can use a tag to let others know you have the same book posted under a different ISBN.  If those looking for this book have their options set for this, PBS does send out emails to let you know a book similar to the one you're wishing for is available; not everyone has their account set for this option.  You can also post your book, then advertise in the WL Books Posted Under Different ISBNs thread in the Book Bazaar.  Just some options for you.

Ok thanks for the ideas.I will see how to do a tag.

They are at the bottom of the book detail page.   I put in some thing like "Also listed as ISBN xxx" 

This often happens if you have a UK or Canadian version of the book. 

Apply your own tag to this book:
