The purpose of Saskatoon Theological Union Libraries is to provide and promote library and information resources in support of the missions and goals of the colleges which form STU. STU Libraries are service-oriented and support the development of academic and religious communities.

Saskatoon Theological Union (STU) Libraries have combined resources to operate as a unified system in 2 locations: Saskatoon Theological Union Library at St. Andrew's College and the Horizon College & Seminary Library. STU Libraries collections consist of over 100,000 monographs, over 6000 ebooks and numerous theological, religious and philosophical digital resources through EBSCO.  Our ATLA database includes a scripture searching tool, allowing users to locate scholarly articles and book reviews on specific scripture, chapters and verses.

In the summer of 2020, the Lutheran Seminary Library, College of Emmanuel & St. Chad Library Collection, and the St. Andrew's College Library Collection were amalgamated and interfiled into one collection, housed at St. Andrew's College. St. Andrew's College Library is now the Saskatoon Theological Union Library. 

Through a joint collection development policy, each library collects in several specialized subject areas, embracing a wide range of theological topics. Each also maintains a general collection of books and periodicals to meet the needs of courses offered by its College. All currently registered STU students, faculty, and staff as well as members of the public are eligible to borrow material from any STU library.
