Series I contains 54 boxes of alphabetically arranged correspondence files. All material is arranged in chronological order within each folder and individuals are given separate listings, provided the file contains six or more items to, from, or about that parson. The correspondence of those who appear one to five times is filed alphabetically with the first letter of the surname in "Letter" general files. Folders containing ten or more items to, from, or about a person are marked with an asterisk (*).
