ISBN and Reversion

[Al Stevens]

I have had the rights to a title reverted to me by the publisher. I have the electronic files including the typeset page proofs in PDF (which I used to do the index way back when). If I decide to self-publish in the same format (trade paperback):

May I assign a different ISBN without making a new edition? (Content would not change.)

-or-

Must I keep the existing ISBN, which is assigned to the original publisher for an out-of-print title?

-or-

Should I make some changes, give it the next edition number and a new ISBN?

It's a new edition, and needs a new ISBN even if you don't make changes.

It's the same as when a large publisher swallows a smaller one; as soon as the print run sells through, the "new" publisher has to issue a new ISBN. You'll sometimes see a statement on the copyright page that says something like "Reissued by XX" with a date and then the ISBN.

If you look at some Dover Press books at a bookstore you'll often find a book with a similar statement, if you want a model.

ISBN uniquely identifies not only the content but the format and the publisher. If any of those things change the ISBN must change also.

Thank you Jim and Med. That's what I needed to know. I've changed publishers in the past when imprints were sold, but next editions always involved rewrites, and I wasn't sure.
