I was shopping on-line for some obscure DVD's and found an advert for a set I wanted which boasted that it comes in its own "keepcase." I never thought that the little clear-plastic boxes in which DVD's come had a name. I always called it "the box." Keepcase seems not have found its way into many dictionaries yet but it is used extensively on the Net, as I discovered when I Googled it. (Shame, shame, for verbing a noun, Padre.)
