The Marcus J. Borg Papers consist of materials generated and assembled by Borg and reflect his career as teacher, scholar and writer, and department chair. The Papers include materials pertaining to curriculum, faculty evaluations and awards, and College of Liberal Arts committees.
Borg's course materials include reading packets for religious studies courses, syllabi, lecture notes, and reference materials. Other records include correspondence with Al Hundere and his family; materials pertaining to the Jesus Seminar and the Society for Biblical Literature; book contracts and agreements; certificates; sermon scripts and notes; and biographical materials.
The collection includes several photographs of Borg; sound recordings (6 audio cassette tapes that have been subsequently digitized by the Special Collections and Archives Research Center) of presentations by other scholars on topics such as "what the Buddha has to teach Christians", " toward a spirituality of peace and justice", and the "green world"; and computer disks with word processing files for the God at 2000 symposium and other events. The collection also includes several nameplates and plaques.
Approximately half of the collection consists of books from Borg's personal library with extensive annotations and notes.
