The library should know better than to let me keep books for a year (because I taught a few courses some years ago and therefore qualify as faculty). It just means that I keep them for over a year. I've now had The Letters of Caryll Houselander since December 21, 2012. Great book, no wonder I don't want to give it back. But I probably wouldn't have gotten it back on time even if I hadn't liked it, because I'm just shiftless.
