The materials in the Jean Martinon Papers span the years 1923-1994. Reflecting the origin of the materials, the collection has been organized into eight series: Ephemera (Manuscript), Ephemera (Printed), Correspondence, Jean Martinon Society Records, Association Jean Martinon Publications, Published Scores, Unpublished Scores, and Arrangements. In most cases, original folder titles have been retained. Materials within folders are arranged chronologically.
Series I, II, and III consist of Martinon's own papers, writings, correspondence, and other documents. Items in Series I include Martinon's articles, lectures, and poetry; of particular note are the materials illuminating Martinon's interest in mountain climbing. Series II includes programs from Martinon's own performances and from performances of his works. The correspondence files in Series III consist of individual folders of letters to and from fifty friends and colleagues. The folders are arranged alphabetically by surname of the correspondent. Topics include questions posed to Andre Malraux from a group composed of Martinon, Dutilleux, Ohana, and others who disliked the Viennese School and electronic music. Correpsondence dates from 1959-1976, with the bulk of the letters dating in the early-to-mid 1960s.
Series IV consists of materials donated to the Music Library by the Jean Martinon Society when the group disbanded in 1993. The publications in Series V provide much information about Martinon's life and work, including volumes of photocopied interviews and articles, reviews of recordings and performances, and a catalogue raisonée of his recordings. Much of the Association Jean Martinon material is in French.
Series VI contains fourteen folders of published scores. Two scores have the same opus number, Introduction et toccata, op. 45 and Symphonie no 3 "Irlandaise", op. 45. The Jean Martinon Society lists the first composition as op. 44. However, in examining the score of Introduction et toccata, it clearly is marked as op. 45.
Five boxes constitute Series VII, consisting of unpublished scores, including two compositions that were never published, En Promenade and Déchiffrage pour hautbois.
Series VIII contains three folders of Martinon's arrangements of music by Bach, Beethoven, and Paganini.
