Oh My Dear Secret Santa! I don't know how I missed your message from late October. No, I wasn't studying my workmate's, er, educational cards and literature (she said, batting her eyes demurely). Honest, I was just trying to help out a fellow librarian! All right, I did count it as a reference question for the monthly statistics, but I never even saw the goods. Really.
As for those wonderful cards you posted, I have the older ones, and Guide Cats II as well. {Many thanks to Camsco and Old Songs Folk Festival}. I'm drooling over the newer titles, though. Belive me, I study such of those cards as I have, and review them regularly.
