Dear Ms. Kautz,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located one file Fiscal Year 1989: 109-1 Army and Air Force Records Study [Correspondence and Reports Relating to Processing Records of the Vietnam War] from the series Program Subject Files, 1978-2003 in the Records of the National Archives and Records Administration (Record Group 64). The records are not yet digitized and available in the Catalog. For access to and/or copies, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
Using the Record Group 64 records, we determined that Vietnam records were accessioned into NARA custody on April 27, 1987; and the first segment of records were processed and open for public research on April 27, 1988.
We hope this is helpful.
