This post about the term graphic novel reminded me that I've been meaning to write something about the vagaries of terminology.
I'm British, but working primarily with American students, so that's one language divide right there, but I've been talking with various people about library management systems recently, which throws up a whole other array of library-specific terminology choices.
"I want to to borrow / loan / check out / book out / take out this thing, so I'll use the self-check / self-issue / self-service machine or point or station."
"Someone else has an item out at the moment, so I'll request / recall / reserve / book / trap / wait-list it."
"The book we all need to read for our paper is in the reference / reserve / non-circulating / no-loan / closed section, so no one can take it away."
At least renew is pretty stable, although I have heard 're-check'!
It would be invaluable to know which terminology is the most meaningful for our specific users, but it's hard to get that kind of feedback - I suspect most people really don't give it that much thought. Common questions and misconceptions do provide some clues, though - something to use as the basis of experimental changes, at least.
Which terms do you use? Anything else to add to the lists, or ones that you'd never heard before?
