Library card and that are two different things. At first, I thought I could go to the study room upstairs with a library card. Only when I went did I know that I had to go to the study room to get the administrator's card. I forgot how much it cost. It seems that I have a monthly card and two monthly cards, and some longer ones, which are more suitable for holidays. Usually, I only travel a few times and then I waste it. . .
There are 30 and 50 library cards, and 50 can borrow books from any floor. Among them, 20 pounds is the deposit. You can get a refund when it expires.
