Response: I know this is 2 years late but I'm sure I did everything that the swap required, and that was : 1) A photo of the FRONT of the library showing the name on it. 2) A photo of the lobby or what your partner would see if they walked in. 3) A photo of books in the writing section (call numbers are in the 800's). Can either be a closeup of a few books or a long shot of the stacks. I know I did all three and I think I took a few extra. I understand that I made the mistake of sending via snail mail by accident but I believe that has to be the only reason that I got a three.
