These records have not been digitized. Under normal circumstances, you could view the microfilm at the research rooms at the National Archives at Washington, DC. You also could use the Microfilm Catalog to order reproductions, for a fee. However, as a public health precaution, all National Archives research rooms nationwide are closed to the public until further notice. The National Archives has also suspended the option to place orders for microfilm reproductions.
If you have additional questions about these records, please email the National Archives at Washington, DC - Textual Reference (RDT1) at Archives1reference@nara.gov.
