The Oak Lake Writers' Retreat Records document the activities and impact of the Oak Lake Writers Society, particularly their summer retreats aimed at supporting Native American writers, educators, and storytellers. Spanning seven boxes, the collection includes correspondence (notably between Charles Woodard of South Dakota State University and retreat applicants), writings produced during and about the retreats, application materials, grant and funding documents, educational resources, and administrative records.

The files encompass a wide range of themes such as environment, economic development, Indigenous education, mentorship, cultural heritage, and community empowerment. Notable contents include retreat histories, newsletters, reflection papers, photographs, and records on special events such as the Indian Education Summit and the Anniversary Conference. Recurring documentation of specific individuals (e.g., Lowell Amiotte, Joyzelle Godfrey) and locations (e.g., Enemy Swim Course, Devils Tower) also provide personal and geographic context.

This collection chronicles the development of a key cultural and literary initiative that nurtures Indigenous voices in the Northern Plains. It reflects the collaborative efforts between tribal communities and academic institutions to promote Native literature and cultural preservation. The records offer valuable insight into contemporary Indigenous literary movements, community-building through creative expression, and the intersections of education, environment, and Indigenous identity.
