Yesterday, A librarian at mpow pointed out my redundancy in saying "isbn numbers." Which means I've been digitized and preserved for history to ponder - as being redundant.
The good news -- I don't think I can possibly misspeak again (with those terms at least) given my mortification at the moment.
Strategies: I already shorten AACR2 down to "Acer Deuce" - so perhaps I will follow that up with "Iz-bin."
Do you also say "ATM Machine"? :)
