ISBN transfer

ISBNs aren't transferable. They each refer to a specific edition of a book. So no, you can't transfer this ISBN, you'll need a new one for the new publisher.

I am concerned, though, that you have this ISBN but suggest that the book wasn't published and no contracts were signed. This isn't at all usual.

I've never seen an ISBN assigned until it's published. May want to get with the publisher who assigned it and see what's up.

ISBNs are often assigned prior to publication. If they weren't, books wouldn't be able to be listed anywhere until they hit the shelves, which would make it impossible to order them in order for them to reach those shelves.

They are also sometimes assigned to books before contracts are signed, if publishers are very keen. I've had this happen to me a few times, once by a very reputable publisher. It shouldn't happen, but it does.

Having said that I am concerned about why this particular publisher assigned an ISBN to the OP's book: it does sound a bit worrying.

If you self publish with createspace, you are assigned (or provide your own) ISBN before you can even get your proof copy. They will not even review the files without it, and it can't be officially ''published'' until you have the files reviewed and proofed. So yes, it is assigned before publication, which may be why the OP says the book was never published.

Woops. Just realised this is an old thread. So sorry!
