One of my staff members stopped me today to show me this picture. Last week an ARS student found a mysterious packet inside a book along with unpleasant staining on the pages. After putting on some gloves they opened it and found this (yes it's a fish) 
Mystery solved! In the late 70's or early 80's SCU had a rivalry with St Mary's. One evening some St Mary's students drove here & distributed wrapped sardines through the card catalog & reference books. We thought staff had found all the fish, but it seems that they missed one.
For those curious, the book it was found in is "Afro-Braziliana : a working bibliography" (from 1978)
