I am away from home for the summer, so I put my account on vaction hold, and made sure none of my wishlist books were on auto request. I got online for the first time in a awhile and noticed that one of the books that was on my wish list is enroute to me? I did go back and double check that none of my other wishlist books were on auto request?

I won't be able to get to a computer again till next week, so hopefully that is the only glicth I encounter this summer.

Did you add it to your WL after you put your account on Vacation Hold? If so that book would not be covered under the hold and the order would be put through. Here is the portion of the Help Center that explains it better than I can:

If you place a book on your Wish List while a Hold is in effect, that Wish List item will not be hidden by the Hold.

Think of your non-auto-requested Wish List items as a birthday present.   Whatever is on your Wish List will be "wrapped up" by the Hold when it goes into effect, and the birthday present will be "hidden" from view by the Wrapping; anything placed on the birthday present after it has been wrapped (any newly Wishlisted books) will not be hidden from view.  This analogy also applies to how the Hold "hides" items on your Bookshelf. 

Auto-request items are not hidden by the Hold; however, they will be treated like they are hidden if you have no credits at the time a copy of the book becomes available when your account is on hold.

But Cheryl when you put a book on the wl it starts out with no auto request. You have to change it to yes so even if that was the case it would not have been on auto so it would have given the 48 hours and would have timed out.

The book must have been posted just before you placed your account on hold and was in the system as requested by you.  If the poster let the request sit for 5 days and then chose the last mailing date, that's 10 days there.  Plus the 2 day mark it mailed grace period could theoretically stretch it out to 12 days.

Joan, with all these wonderful explanations, and while true, there *were* glitches reported back when PBS put the new Wish List system online. So bottom line, those nasty computer gremlins (or glitches) *do* still exist and it could have been just that!  =D

Cheers!
