Arthur B Johnson collection is comprised of different materials he collected over the course of his career. Not only collected, but wrote in correspondence to government agencies, forestry departments, and local newspaper articles affiliated with western culture.

The collection begins with a variety of over 30 geographical maps of Northwest National Forests ranging from the 1960s to the 1990s. It then turns to three publications by Ralph Space titled The Clearwater History which recount the personal and collective history of the Clearwater region and people living in the area. Johnson’s personal opinions and responses to newspapers, articles, and government agencies (some of which were published). Then the collection ends with a variety of dated folders which contain Johnson’s notes of events happening during his career that he took interest in as well as articles which he authored and were later published.
