MB3 is an exclusive APP for readers who use the M7 library automation system and want to use mobile services. Since MB2 is no longer updated and maintained, it will be replaced by MB3. MB2 is expected to be removed by the end of 2022.

In 2022, the newly upgraded and revised MB3 mobile library system has corrected the user feedback problem of the old version, and provided:
1. Basic library services, such as: collection inquiry service, book recommendation, venue/equipment reservation, self-service quick loan, electronic loan card...etc.
2. Book classification query services, such as: new book announcements, special collections, designated reference books, etc.
3. Personalized services, such as: my loan, my book cart, my appointment, my file, my recommendation...etc.
