The Kearney W. Barton collection of Northwest sound recordings primarily consists of original recordings engineered and/or produced by Barton at Audio Recording, Inc., his own recording studio, which operated out of various locations in Seattle, Washington from 1961 through the late 2000s. The bulk of the collection is comprised of music recordings, but also contains a smaller percentage of spoken word recordings, as well as radio advertisements (many of which also incorporate music). Specific audio formats represented in the collection include: open reel analog tape, compact cassettes, analog sound discs (7 inch, 10 inch, 12 inch, and 16 inch), magnetic wire records, and compact discs. The collection also contains a small amount of manuscript material, which mainly consists of technical notes that were found with some recordings and very limited correspondence (chiefly from lawyers). In some instances, notes included on original containers also have been preserved when material has been rehoused.
