Look for the books you want to borrow first, and look for them in the stacks on the second floor. Undergraduate students can borrow up to five books at a time, among which I am literature and art. I can borrow up to two books at a time for two months at a time. You can renew them online for two months. Now you use a smart card, so your meal card will do. You can't borrow it on Saturday, and the library staff is off. In addition, if you want to borrow the secret stacks, you should first check the serial number of the books on the computer (the second floor of the library), then go to the stacks on the first floor and borrow them on the second floor after you get them. After borrowing, the secretary has to degauss. That's about it. You'll know when you come.
