The collection consists of Brown's correspondence, notes, images and maps relating to his field work, papers of his second wife, Lilian Brown, drafts of unfinished autobiography, notes and illustrations for his scientific articles, records of his work for the museum, including exhibition halls, records of his commercial work as well as reports from his consulting work for the goverment. The collection also contains papers of Peter Kaisen who was a long-term Brown's assistant.

The Department of Vertebrate Paleontology began sending staff into the field as early as the first year of its founding, 1891. Since then the department has organized and supported decades of seminal field work as it continues to do so today.
