Would the student who borrowed the Cavalerro Collection Catalog from [edited], the curator for the Compton museum, please return this item at your earliest convenience.
I'm assuming when they say "borrowed" they mean "stolen"; why else would they send out a mass e-mail? Unless the curator can't remember who he gave it to, which doesn't seem very likely, knowing him.
The catalog contains an entire listing of all of the taxidermic animals donated to the university a few years ago by a wealthy benefactor. The catalog also has comprehensive information about the insurance values of each piece.
