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 acknowledgment as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
In regards to the annual report, we searched HathiTrust and located the 1956 Annual Report of the Interstate Commerce Commission.
