You can extend a due date up to three times. Please use Library online services (My OPAC) in the website of Central libraries. Be careful that you can't renew materials that have already been reserved.

Please return overdue books immediately. In case it's overdue, you won't be able to borrow other books in all the libraries.
ex) three days overdue × two books = suspension for six days

No, the Cenreal libraries's borrowing policy is the same as usual even in a vacation.

Talk to staff at the library. Generally, we will ask you to pay the same price as what you've lost or soiled.
