I recently had a Wish List book posted and accepted.  I was checking the other books in the series on my Wish List and noticed the other editions of that particular book had not been placed on hold as they used to be.  Strange glitch or have any other folks run into this?  It's not a huge problem, but with the expanded Wish List it does mean I would need to watch a bit closer.  TIA!

Not all versions of a book are linked, unfortunately, and if they aren't, they won't be automatically put on hold. You can submit a request to the Data Team to have different versions linked, providing them with the ISBN numbers of all copies that need to be linked.

Just remember to only send them the listings with true ISBNs.  The non-ISBN listings aren't linked, since they are supposed to be a 'one-shot-deal'.  Several years ago, they told me that I only needed to send one ISBN as they would be checking for and adding all others when they did the link-up.  However, being only a 'bit' ocd, I usually add a note such as 'an audio and 2 pb listings aren't linked'....
