The Mary S. Thelen Library is a modern library facility that is dedicated to supporting the study, learning, teaching, research, and training needs of DMU students, faculty, and staff. For more information about the vision, mission and biography of Mary S. Thelen, view here.

Established in 1999, the Library’s mission focuses on continually growing its collections and resources to become an academic research library for materials on or related to integrating clinical psychology and Catholic/Christian theology. The Library, named in memory of Mrs. Mary S. Thelen, will grow to include more items, within its seven major collections:

    • Circulating Collection
    • Reference Collection (print and electronic reference materials)
    • Reserves Collection
    • Serials Collection (print and electronic journals)
    • Psychological Test Collection
    • Media Collection
    • Archives & Special Collections

In addition, the Library provides access to full text electronic and online databases in the psychological, social and behavioral sciences, theology, and philosophy; computer workstations; audio/video equipment; and independent learning resources. DMU will continually make significant expansion of these resources and associated services in the upcoming academic years.

In addition to increasing the collections in the core area of clinical psychology, each year using the ongoing three-year Special Collections acquisitions cycle, there is a focus on acquiring materials related to the ‘three pillars’ of the DMU curriculum – Integration (of clinical psychology and Catholic/Christian Theology), Theology and Philosophy.

The Thelen Library also enhances available resources by facilitating access to the collections of other libraries in the Metropolitan Washington area, and participation in various resource sharing activities with other libraries through  OCLC, and membership in the Virtual Library of Virginia/Virginia Independent College & University Library Association (VIVA/VICULA).
