I have a WL book.  I was going to post the book, but the ISBN I put in shows the book as a paperback when in fact it's a hard cover.  The ISBN for the hard cover doesn't match the one on my book.

I don't know what to do.  Should I post with the ISBN on the book or should I click the 'no this is my book' button which gives an ISBN that doesn't match my book?

I checked, both the paperback and the hard covers are WL'ed so I don't want to post the book incorrectly as I don't want to disappoint the member getting the book.

Thanks for the help/input.

Never post a book using a different ISBN than is actually on it. Title, author, ISBN, and book type all must match.

From the Help Center:

Publishers sometime choose to assign the same ISBN to multiple versions of a book.  However, PBS can attach only ONE booktype to the listing for an ISBN.  If your book does not have the booktype assigned to the ISBN in the PBS database, you will need to post it with a customized listing, using the Post a Book Without an ISBN link on the Post Books page, so that the booktype matches your book.

Solution: You will need to post this book with a customized listing for the book, using the Post Books without an ISBN link on the Post Books page.

You have only one option on posting this book into the system - as a book without an ISBN. Any book you post on PBS must match the system listing on 4 key points - ISBN, title, author and binding type. Unfortunately, the posting will not be offered to the people in the WL line. Sometimes people WL a specific ISBN and book type for a reason. You could apply a Tag to the WLed hardcover version "ISBN XXXXX is the same" or something to that effect and/or advertise it in the Book Bazaar.

Here is the Help Center doc:

When do you need to Post a book using the Post Books Without an ISBN feature?

• When your book has no ISBN
• When your book's ISBN is unknown to the PBS database (has not yet been added by regular updates)
• When your book's ISBN "brings up" another booktype in the database
  • Such as the paperback if you have the hardcover, and vice versa
  • Such as Large Print when you have the regular-font version
  • This happens when the publisher assigns the same ISBN to multiple booktypes).

If your book does not match the listing information (title, author, booktype) in the database for the ISBN on the book, it must be Posted without an ISBN

To post your book without an ISBN:

• First, make sure to look over your book really well
  • Sometimes ISBN numbers can be found in unexpected places like the spine
  • The back of the book and in the publishing information in the front of the book are the most common places to find an ISBN.
• If your book has no ISBN (or the ISBN you have doesn't work in the system):
  • Go to the Post Books page
    • From My Account: click the Post Books tab
    • From anywhere on the site: place your cursor over My Account on the toolbar at the top of the site and click Post Books in the menu that drops down.
    • From your Bookshelf, click the link "Post Books" at the top of the page, in the yellow bar.
  • On the Post Books page:
    • Click the "Post a Book without an ISBN" link at the top of the page, in the yellow bar.
    • Enter the information about the book in the form that comes up:
      • Mandatory information includes: title, author, book dimensions, Subject (genre), booktype
      • Optional information includes: Large Print, Homeschool, Publisher, # pages, Back cover Description (synopsis of the book content), Book Cover image.
      • Your Book Cover Image needs to be less than 5 MB in size, and in .jpg format.

When you are done, your book will be listed in the database with a customized listing that has a "short ISBN" or "PBS ISBN", which is the 5 or 6 digit number that PBS assigns in place of the ISBN to keep track of the book in the system.
