If you’re not busy helping Library users, you should be pro-active helping students look up material.
If someone doesn’t know how to look up a book, either Reserves or in our regular collection, take them to the computers at the end of the counter if time permits – if you send them to the computers without going with them they usually don’t even know what they’re looking at.
So, not helpful.
If there’s a line waiting, use your own computer to show the student the process. You can let them know that they need to do it themselves next time.
