Dear Ms. Lahiri,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series Ration Tickets, ca. 1880 - 6/19/1909 in the Records of the Bureau of Indian Affairs (Record Group 75) that may contain the information you seek. Since Agency records contain all their predecessor Agency records, Red Cloud Agency records will be filed under the Pine Ridge Agency. For access to these non-digitized records, please contact the National Archives at Kansas City (RM-KC) via email at email@example.com.
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 RM-KC. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
