There’s something about a collective noun. They are quite odd and often funny. Christchurch City Libraries has a cool page of collective nouns for groups of animals. I like the idea of a flange of baboons and a crash of rhinoceroses.
At conference time Christchurch will be thrumming to the rhythm of lots of librarians. What could we call these groups of librarians en masse? My coinage is a susurrus of librarians (see the rather nifty All sorts collective nouns site for other librarian collective nouns and more). Got any suggestions?
