Due to adjustments to the digital certificate authentication mechanism, the university's account authentication system is currently undergoing configuration updates and restoration work. As a result, some library services are temporarily affected.

I. Affected Services

• Personalized Library Services: Services requiring account authentication, including viewing borrowing records, placing holds on library materials, and renewing loans online, are temporarily unavailable.
• Electronic Resource Services: Full-text access to and downloading of electronic journals, e-books, and databases are temporarily unavailable. However, on-campus access to electronic resources and searches of the library catalog remain unaffected.

II. Temporary Measures To protect borrowers' rights, the due dates for all library materials originally due between Monday, November 2, and Wednesday, November 4, will be automatically extended to Thursday, November 5. No action is required from borrowers.

III. Service Restoration The relevant university units are actively working to resolve the issue and conduct system testing. Affected services will be restored as soon as the necessary work is completed and normal operation is confirmed.

We apologize for any inconvenience this may cause and appreciate your understanding and patience.
