The Chang Ching Yu Memorial Library is one of the most prominent buildings on the CYCU campus. The building was honored with the Distinguished Architectural Design Award and the Gold Medal Award by the Taiwanese Provincial Government and the Journal of Chinese Architects, respectively.

The library is a six-floor building with five floors above ground level and one basement. The gross area of construction is about 11,900 square meters. It has 1,499 seats available.

The entire library currently houses extensive, various and comprehensive collections to support teaching, learning, and research activities. The facility also provides a comfortable environment for students, faculty, and staff to study and discuss at the CYCU campus. Furthermore, the library established the "Christian Culture and Literature Collection" center, featuring many vital ancient Christian records and relics. It is now home to many researchers who devote themselves to Christian culture studies in Taiwan.

In the summer of 2017, the library upgraded its automation system to support the daily workflows and provide better-integrated resource management with a better and more consistent user experience.

Today, more than a million copies of digital resources of online journals, databases, and e-books are available. In addition, the library integrates an online Discovery Service on the Library website to provide users a unified and coherent means of accessing all the resources through a single search. The library also provides electronic newsletters, arrival notices of new materials, and circulation notices. All the services mentioned above are available on the main web page of the Library website.( https://www.lib.cycu.edu.tw/ )
