Dear Mr. Green,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located Muster Rolls and Rosters, 11/1/1912 - 12/31/1943 that may contain rosters for the units stationed at Camp Cody. Some of these records have been digitized and may be searched online through the Catalog by name of unit. The remaining records are not yet digitized. If you need assistance locating a specific unit, please contact the National Archives at St. Louis (RL-SL) via email at firstname.lastname@example.org.
We also located a number of other records related to Camp Cody and the 34th Division during World War I. Some of these records have been digitized and may be viewed online through the Catalog. For more information about undigitized records, please contact the reference unit listed as the contact in the Catalog description.
Photographs of various U.S. Army and subjects during WWI are in the custody of the National Archives at College Park - Still Picture (RDSS). Please contact RDSS via email at email@example.com. Their web site is Photographs and Graphic Works in College Park, Maryland.
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 RL-SL, RDSS and the other NARA units. We apologize for this inconvenience and appreciate your understanding and patience.
We also searched the Library of Congress’s catalog and located several photographs and other items related to Camp Cody. In addition, we located a number of photographs relating to Camp Cody on Wikimedia Commons, to include the following “Animated Crest.”
We hope this information is helpful. Best of luck with your research!
