All keys that leave the circ desk should be checked out in the system. If you loan out a key without a barcode, you are responsible for ensuring its return.
If you are concerned that any departmental/office keys are still checked out at closing, search the catalog by title “keys” – and follow up by email with the student who has the key. Please copy the library circulation mailbox so that the next supervisor on shift will be aware of the situation.
No need to add checking offices to your closing routine – but use your best judgment in individual situations.
If the key is in fact missing and not checked out to anyone, please change item status to “missing” and email the lib circ mailbox.
The expectation is that student workers from other departments only work during open hours – and should return before closing.
