The Cage Correspondence collection is comprised of correspondence and ephemera including letters, cards, clippings, catalogs, photographs, negatives, cassette tapes, music scores, and art.  Early materials focus on family correspondence and newspaper clippings and are interspersed with Cage's own notes and manuscripts.  Later correspondence is enhanced through Cage's use of "Note-o-Grams" which provides carbon copies of his sent messages.

This is correspondence that is related to John Cage but was not given to Northwestern by the composer. Letters are between Cage and the person in the folder's title unless otherwise indicated in the container list. Of particular interest are letters from John and Xenia Cage to friends in California that relate their experiences while living in Chicago in the early 1940s.
