Also this might seem like a silly question, but are you allowed to bring food/drink into the library? (obviously not messy foods)
and do you need any ID card/ membership to use the library?
Depends on the library. Hargrave has a no hot food policy. Most have normal food policies, so avoid anything that smells, messy or sticky food (just to be considerate, though most uni students may not abide by this) and you’re all good to go. Most will have signs whether they permit hot food or not, or even food at all.
As for ID, no. As long as you’re quiet, you don’t really need ID as far as I know. Of course, it’s a different story if you want to borrow things or print stuff.
Could you please recommend which libraries/ buildings are the most quiet and have good sized tables?
Typically Law Library is the best bet for a high school student. Lots of quiet spaces, close to the bus loop and generally a powerpoint at most tables. Higher floors are quieter. Would avoid the small side room on the first floor, if my memory serves me correctly, as this is where the group study and tutoring occurs.
Matheson library now has more study spaces since its refurbishments so there’s sometimes a spare space there every so often. Has less powerpoints though, but is quite the spacious area, so will give it a mention.
