15 microfilms (6.5 linear feet and 1 oversize folder) — 5.5 linear feet — 3 oversize volumes (not microfilmed)
The Crapo papers have been arranged into the following series: Correspondence; Personal and Biographical; Political; Business records; and Miscellaneous (mainly financial). The collection relates primarily to the career of Henry H. Crapo with the files dating after 1869 pertaining to the business activities and political activities of his son W. W. Crapo.
In 1992, the bulk of the Crapo papers was microfilmed. This finding aid begins with a listing of the contents of the microfilm followed by a container listing of those portions of the collection which were not microfilmed. For reasons of preservation, the researcher should use the microfilm copy. Access to the original materials will be limited to the unmicrofilmed portions of the Crapo papers.
