* WPA =  Works Progress Administration, later called Works Projects Administration.

The Historical Records Survey (HRS) was a project of the Works Progress Administration New Deal program in the United States. Originally part of the Federal Writers' Project, it was devoted to surveying and indexing historically significant records in state, county and local archives. The official mission statement was the "discovery, preservation, and listing of basic materials for research in the history of the United States."
