Library cats, that is. I remember reading something about this - with charts - in The Whole Library 4 reference book. Basically, the data answers the following questions:
1. how many libaries have, or have ever had, live-in library cats?
2. what are the names of the cats and how long did they reside at their libraries?
3. are the cats real cats, stone library lions, ghost cats, or stuffed big cats...?
Now this important information is online, in a visually interactive format. Yes, INTERACTIVE LIBRARY CAT MAP! Say it three times fast. Found it Neatorama.
I'm happy to report that Massachusetts have a few currently living library cats.
