This series contains Hamilton Fish's correspondence. Most are in-coming letters but the collection includes Fish's own out-going mail, either as originals or duplicates, which were collected and inserted in the collection. The duplicates are mostly photostats, but there are also handwritten and typescript copies. These are identified as [COPY] in the inventory. Item descriptions are, for the most part, according to the brief abstracts in "A Calendar to the Hamilton Fish Papers" prepared under the direction of John Bassett Moore; however, not all letters in the Calendar are part of the collection. Only the letters collected here as physical items, originals or copies, are included in the inventory for this series. There are also letters in the collection that were missing from the Calendar and have been added. For some letters, there is additional description, which came from "A Digest of the Hamilton Fish Papers." The Digest also includes letters that are not part of this collection and those descriptions have been omitted. Both of the earlier inventories can be found in the legacy finding aid.
