It seems that all of the boxes have been moved or are no longer there.

Found #3 and 4

Nice Series.

After failing to find the first 6 stamps I looked for, I finally found #6 where it was supposed to be. I then went back and looked for the other 6, managing to find 3 of them (but none of them where they were supposed to be -- #7 was only one shelf away, but others were as many as 3 shelves away). I checked all of the shelves on either side of #1, #2, and #5, as well as the shelves on the backside of those books and the shelves directly opposite, all fruitlessly. The remaining three stamps may still be there, but I have no idea where they might be now. BTW, the four stamps I found have all been restored to their correct locations.

We looked for 4 out of 7 of the stamps and could not find any of the stamps. We think the stamps are missing. :(

I love Library boxes but these were very hard. Got 2 though.

Oh my goodness, such fun!!! Found 3, 4, 6, and 7! Thank you for the hunt!

Such a cool idea! I love books and libraries, and it was fun to wander around such an amazing library to find fun stamps!

I didn't come prepared so I looked these up while in the library. The first I didn't figure out, yet. The second had a magnet but no stamp. The other two I didn't find I thought I had the correct location but didn't find anything there.

I like the three that I found. I may have to do this in my local library.

I could only find #4 & #7. #2 is still missing the stamp. But is was a beautiful library!
