Readers can use the Recall Borrowed Books service to request books that have been loaned by other readers. If the circulation status of a document is "loaned", readers can apply for the Recall Borrowed Books service via the OPAC platform or the WE Library WeChat mini-program. After the application is approved, the reader who currently holds the document cannot renew the loan. When the document is returned to the Library, the system will send a notification via an email to you, informing you to come to the Library and get the document as soon as possible. Readers can view their Recall records via the WE Library WeChat mini-program or library portal.
