By far the largest subseries in the series, the correspondence subseries contains alphabetically organized files of correspondence between the staff of the HWRD (primarily Kathryn Stidham/Culver) and potential or actual donors of materials to the collection. The files also occasionally contain letters requesting materials from certain organizations when no response was received. Also included are files of correspondence between Stidham/Culver and other depository staff members or leaders, including Executive Committee Chairmen Kuykendall and Murphy as well as neighbor island depository representatives Elsie Wilcox, Franklyn E. Skinner, and Ernest de Silva. Single files were maintained for individual letters of the alphabet and alphabetical organization was not maintained within files. There are guide pages within many folders listing the names of the people or organizations with correspondence in that folder. When there was a significant amount of correspondence with a specific organization or person, separate files were created for this person or group.
