The picture above...

I found the picture of Jerome on Wikipedia's article about the artist, Niccolo Colantonio. I thought the picture would be appropriate, given Jerome's status as the "patron saint of librarians." The books in the background serve as witness to this status. Perhaps the fact that he is extracting a thorn from the lion's paw is also appropriate, given the number of times librarians have to extract thorns from growling patrons' paws!
