USPHS Office of the Director Central Files: NARA RG 090 (1945-1950) Identification

SUMMARY

This dossier investigates the specific series and box numbers within National Archives and Records Administration (NARA) Record Group (RG) 090 that contain 'Office of the Director Central Files' or similar administrative correspondence for the U.S. Public Health Service (USPHS) from 1945-1950. The core inquiry seeks to identify the precise archival locations for these records to facilitate further historical research. As of this report, no direct sources specifying these exact series and box numbers have been retrieved, leaving the identification of these records as an open question requiring direct archival consultation.

STRONGEST CASE FOR

To locate administrative correspondence from the USPHS Office of the Director between 1945 and 1950, a researcher would logically consult Record Group 090, which is officially designated for the Records of the Public Health Service. Within this Record Group, standard archival practices suggest that central files and high-level administrative correspondence would be cataloged under series directly related to the 'Office of the Director' or similar top-level administrative functions, likely organized chronologically or by subject. Therefore, a targeted search within RG 090 for 'Central Files' or 'Office of the Director' series for the specified period is the correct approach to finding these records.

STRONGEST CASE AGAINST

While RG 090 is indeed the correct Record Group for USPHS records, the precise series and box numbers for 'Office of the Director Central Files' from 1945-1950 are not immediately apparent without detailed archival finding aids or direct consultation. Archival organization can be complex, and records might be interfiled within broader administrative series, or the terminology for 'Central Files' might differ. It is possible that records from this period and office are not explicitly labeled as 'Central Files' but are instead part of broader administrative or general correspondence series, making a direct search for the exact phrase potentially insufficient.
