MOD（Multimedia on Demand） is a collaborative system developed by the libraries of the University System of Taiwan (which includes the National Tsing Hua University, National Central University, National Chiao Tung University, and National Yang Ming University).

The Library has 10 personal computers in the AV center on the 8th floor. You can use these computers during library hours to browse online AV contents through the server. The system can be used by multiple users at the same time, and provides a dynamic, active, and interactive service.

Through close collaboration, the libraries of the University System of Taiwan have integrated their AV multimedia materials and course videos to facilitate online-learning in the four universities and share their AV multimedia materials.
