I find that “anthology” + “cats in libraries” or “library cats” gets no results in search. That seems like a large gap in the weird/fantasy story-anthology theme-o-scene. Think of the creative possibilities… weird, intellectual, macabre, historical, comedic.

The closest I can find is the title “Cats, Librarians, and Libraries: Essays for and About the Library Cat Society”, from the librarians. That was from way back in 1992, and appears to be unobtainable now. Further investigation finds it was 42 pages, and more of a convention booklet. Though it was obviously nicely presented…
