Mystery Solved!

Tip InKara says:  This piece of paper sat on my truck of mysteries for several months. It was given to me by the circulation staff—who perhaps found it lost and lonely in the stacks or in a pile of books. Thanks to the Internet, I was able to track down the book I thought it might have come from—we had two copies of the book and it’s quite popular and often not on the shelf. Not wanting to interrupt patron use of the item, I bided my time. Several months ago, I determined it did not come from the other copy of the book. That copy was intact and complete, but this copy has only recently returned to the shelves. I am happy to report that the missing page and its book are now reunited again! We will tip the missing page back into the book and it will be as good as new.
