My official title was "Library Technician" because I had all of the same duties and responsibilities as folks that actually went to school for it without the degree. There was a point when they did almost 100% reimbursement for library science courses but too many folks abused it so they dropped it to like 50/50.

My only real advice is don't let them push you up the chain of command before you really understand what's going on at the circulation desk. I suppose that could be true in any job though. The higher ups forget what it was like to be a little person.
