Dear Ms. Sittig,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Central Correspondence Files, 1936 - 1950 in the Records of the U.S. Maritime Commission (Record Group 178) that includes 16 file units pertaining to Brunswick and may contain information about the construction of Liberty ships. For more information, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
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. We apologize for this inconvenience and appreciate your understanding and patience.
We suggest that you review the Naval Heritage & Command Center; Library of Congress Shipyards, shipbuilding, and liberty ships, ca. 1942; and the National Park Service Liberty Ships and Victory Ships, America's Lifeline in War (Teaching with Historic Places) websites for additional information and/or resources.
You also may wish to review Savannah, Brunswick played an important role in Liberty ship construction for more information.
We hope this is helpful. Best of luck with your research!
