The ACTS library was first established on Seodaemoon campus in 1974 with the U$100,000.00 contribution from the Billy Graham Foundation. Later in 1982, it moved to YangPyung as is still today. In 2004, it had opened a newly built library, which provides a spacious and pleasant environment for its users.

There are about 95,000 volumes, 230 different kinds of periodicals, 15,000 theses and dissertations, 15,000 reference books, and other assigned books and guideline materials newly acquired, organized, and classified.

The library also provides inter library services in connection with other Korean theological university libraries, National Assembly Library, and National Library of Korea. Further, it has an access to a rich body of electronic resources through American Theological Library Association (ATLA) which offers more than 660,500 journal articles, 266,410 essays from 18,800 multi-author works, and 602,500 book reviews. It provides research materials through web DB such as DBPIA, KISS and e-article.

Most of the lecture rooms are digitally equipped with wireless internet access. This serves both the faculty and student body to build and develop communal learning communities in and among them.
