Yes. If you have a library card there is no need to ask a librarian, just find a computer not in use and log on as patron. If there is no open computer or you do not have a library card, go to the circulation desk and ask for a computer pass.
There shouldn't be a problem but you would have to ask first to make sure there's no schedule nor anyone else be on there before you.
