Series 1, Correspondence (1897-1981) consists mainly of personal and business correspondence. Some of the documents are not letters per se, but they relate to correspondence Baldwin had and for this reason have been included in the correspondence series rather than with the subject files. This series gives a fairly complete picture of the diversity of Baldwin's interests, for his correspondence touched on all areas of his life. However, Baldwin had few long-term correspondents, perhaps detracting somewhat from the richness of the materials in this series.
