I have many older advanced copied of books lying around in mint condition. These are at least 5-10 or more years old, and the actual novels themselves have long since been released. Am I still not allowed to post them?

Thanks.

I wouldn't think so. If they were advance copies, there's nothing that's changed to make them anything different. The problem with advance copies, is that they are sometimes sent out prior to final changes, and there may be something changed afterwards making them different than the final publication.

The only way to offer ARCs is in the Book Bazaar as a freebie or a free bonus with an order.

Alison, try listing them here!

They aren't allowed because the book might have had parts rewritten or edited or something before actual release.  Not because the book wasn't out yet. So they aren't allowed.  You can offer them as a freebie with an order from your shelf.
