1075 A Peep of Librarians

Somewhere I've seen a collective noun for a group of librarians congregating. Everything the librarian tells you has previously been worked out in a meeting--even the pauses and punctuation. What would be your vote? I'm not giving a right/wrong answer, because I can't remember, but here are some of my favorites:

a peep (chicken)
a troop (fox, giraffe)
a kindle (kitten)
a gaggle (geese)
a mob (kangaroo)
a pride (lion)
a sleuth (bear)
a school(fish)
a tittering (magpie)
a convocation (eagle)
a chatter (budgerigars)
a trip (reindeer)
a gam (whale)
a brace (duck)
a descent (woodpeckers)

One time when MLA met in Chicago, a tittering mob of us veterinary librarians (out of school) with kindled appetites trooped to a white limo and chattered all during the trip to the Cheesecake Factory where we showed a little gam as we mobbed the restaurant line and braced for a long wait.
