I'm confused....

How is it, that a book I have had on my shelf for ages, is suddenly on wish list hold?

It kind of threw a wrench in my plans.  I was going to the post office this morning.  However when I saw that I might get another order, I postponed going to the P.O. until Tuesday (since it's a holiday).

Just wondering.

I just don't understand how this is possible.

The only way that I know of is that a person that has had their account on vacation hold (or maybe suspended) came back. You can be on vacation hold for as long as you like. If your book was wishlisted when they left, it would still be on their WL when they reactivate their account, even if they've been gone for 2 years and there are now dozens of that book in the system. 

This can happen when suddenly a number of people want a book that only had a few copies posted on the site. The demand outpaces the supply suddenly. Maybe there was an article about an older book that renews interest in that title. Glad that you got another request and can combine the trips into one.

Thanks guys for your response. -- Denise

It would only happen if someone had their Bookshelf or Vacation Hold or Wish on individual Hold. If there were suddenly a lot of orders, any available books would be requested, not go into a wish list hold.

Some people keep their shelves on Hold for very long periods of time. Some also keep books on their Wish List on Hold to budget credits and control the size of their to-be-read piles. I currently have a few books that are available for order on my Wish List on Hold because I have a lot of books on hand to read or they are later in a series I haven't started yet. They were wish listed when I got in line, but have since become available. When I take them off of Hold, if I don't have them on auto-request, the first person in line with the book would see a wish list hold.
