How to use the locker in the library of Shanghai Maritime University: The locker is only used by our readers, and the service period is divided into long-term and temporary. To use long-term lockers, readers need to apply by semester. Each semester is an application and use unit, and juniors and seniors are given priority to apply. Using the temporary locker, readers don't need to apply, just use it with the "campus card" or WeChat applet. Use time is 8: 0015-22: 00 every day. At 9 o'clock every morning, the library staff will clean up the items that have not been taken away in time in the temporary luggage locker to ensure that there are enough temporary luggage lockers for readers to use normally every day. Cleaned projects are considered as unowned projects.
