The purpose of the project was to arrange and catalog the holdings of the archive of the International Horn Society at Bracken Library in Muncie, Indiana. This project required: (1) the devising and implementing of a logical system of arrangement consistent with accepted archival practice, (2) the filing of the holdings in archival boxes, and (3) the compilation of a guide composed of annotated container lists, for use as a finding aid.The guide is divided into six parts: (1) Introduction, (II) Brief History of the Society, (III) Scope and Content Note, (IV) Container Lists, (V) Suggestions for Further Research, and Appendices. The Appendices include two lists useful as an index, and a partial list of contents of the Max Pottag Collection.The International Horn Society was founded in 1970 to foster interest in the French horn, and the archive of the Society was established in 1976. The bulk of the present holdings was collected by Robert Marsh during the academic year 1977-1978, and dates from 1969 through 1977. Among the types of materials found in the archive are correspondence, photographs, tape recordings and phonograph records. Source material on many of the world's most eminent hornists is found in this archive.
