After your hall porter (for when you are locked out of your room), your house mates, your course mates, and your tutor, you should make friends with your friendly librarian. They are a font of wisdom when it comes to finding information, referencing things, explaining how the university works, where buildings are and who to chat to about your problem.
A quick chat with a librarian can often make university a less confusing place. Say hello to them when you arrive and ask them what they can offer you during your stay. They are also adept at finding books that have chosen to hide themselves somewhere in the Library. If you can’t squeeze in a chat at the desk, you can get in touch by online chat, phone or email.
