Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2, RDSS, RDSC & RDSM. We apologize for this inconvenience and appreciate your understanding and patience.
Lastly, we searched the internet and located an article about Richard E. Byrd from the Virginia Museum of History & Culture and the Byrd Polar and Climate Research Center Records at the Ohio State University Libraries. Please search the museum and center for more information about their collections.
We hope this is helpful. Best of luck with your research!
