Sounds like my collection of dances. I have a couple of boxes of cards that I call from at dance clubs. The ones I call at barn dances are just a list, a few short notes but mostly completely memorised.
I need more of a variety for a club evening so learn dances that I like the tune of, or found interesting when someone else has called them, or (pride) thought 'oh, I know how I would explain that'. And a lot of them are dances that I've called once or twice then haven't bothered with.
