Go to Shanghai Library and ask. I got a card more than a year ago and needed an ID card, but I forgot whether it was 10 yuan or 15 yuan. This is a reading card, which means you can read books but you can't borrow books (check them out). There is also a library card for you to borrow books. It is graded. The last time I applied for a card, it was 1000 yuan, and the books in the library were more expensive, like two or three thousand yuan. And 500 yuan (remember), borrowed from ordinary books. You can get all the money back when you return the card (except the reading card), but remember that the invoice must not be lost. Go to the Shanghai Library, where there is an information desk and a small list for you to see. It is easy to run.
