Previously, the users could request to deliver the books from the other campus to their faculty libraries only. From February 15th, 2021, the service is expanded to deliver the books to the General and Kashiwa Libraries too (Komaba Library will be joined after the middle of August). Also, the reserved books can be delivered to the General and Kashiwa Libraries too. Please see University of Tokyo Library System Website.
