I got a book today which has no isbn, says on the front cover "exclusive edition for ____ magazine" and says not for resale on the back. Is this considered an unpostable book? I looked through the help documents but didn't see a specific mention to this problem.

Thank you!

Sounds like it is a promotional copy, which would be allowed.

The issue is the missing ISBN. If it were posted as if it had one (and not a 5 or 6 digit "short" number assigned by PBS), then it would be

• Wrong Book - Wrong Binding/Version
  • this means that title/author DO match but the book does not match the listing's ISBN and/or binding type and/or it was listed as Large Print and the book is not Large Print. Note that cover image does NOT have to match the listing.
  • Inappropriate items - ARCs, pamphlets or leaflets without ISBNs, unbound pages, etc - also fall into this category.

I'd suggest checking the back of the title page to see if there is an ISBN there.

Thanks Sophia! There is a 10 digit ISBN on the back of the title page. I didn't even think to look there! I'll mark it as received correctly then.
