I know we can not post ARC copy books and I always hold back my books that are marked as such but today I came across one of my books that  says nothing about being an ARC but it has no barcode or pricing on the book. I thought this is funny as it is a tradesize of a popular title but we often have ARCs donated to the library so it could be one that's not marked? I have not posted it as it seems funny but I was wondering for future if ARCs are always marked or no?

Sorry if I have posted in the wrong place, I looked around a bit first and didn't see quite what I was looking for.

All of the ARCS I have ever come across are always marked/printed on either the front cover, back cover and/or spine: Advance Reader's Copy or Uncorrected Proofs. Could it be a book club edition?...they never have pricing and sometimes no barcode, an ISBN but no barcode.

Maybe it is a Book Club edition, there is an ISBN on the inside of book but when I looked it up it shows the ardback edition listing, which this is not but the picture did show the Oprahs Book Club sticker.

SOund like its from a book of the month type book club.. All ARCs I;ve seen have it written in some form (uncorrect proof, ARC, reviewers copy etc and have the blurb about it not being the same and not to quote directly frm the book).

Yes, all ARC's I have seen have been marked as such somewhere on the cover (some more obvious than others).  Partially because they also add the info about not for resale, do not quote, and often publication dates etc.

What you have could be a book club edition, or a freebie for a promotion, etc.  So long as the ISBN is printed somewhere on or in the book, you can post it to that ISBN.

I know the paperback book club generally has the HB ISBN inside.  We do need to post them to their own short ISBN if the trade sized PB has a HB ISBN.  I recommend putting a tag on the HB version (if it is WLed) of the short ISBN to help your book move.

Not sure about the Book Club edition (I've never had one myself) but I know all the ARCs I've gotten say ARC on them somwhere, whether on the covers, spine, or as printing on the first page of the book. 

But some have different wording.  It isn't just "Advanced Reader Copy".   Sometimes uncorrected or reviewer's copy.  Or a notice of the publication date on the back near where the ISBN and price would go.

From the help center:

An ARC  (Advance Reader Copy)  is an advance release of a book, usually sent to reviewers before the final copy of the book is published.

• Advance Reader Copies are also known as Review Copies, or Uncorrected Proofs.
• They are softcover books and often carry the same ISBN as the hardcover first-edition that is released later.
• On the cover, they will be marked 'Advance Reader Copy' or 'Uncorrected Proof' or 'Review Copy' and will usually also say 'Not for Sale'.
