====Historic American Buildings Survey====
In 1933, the NPS established the Historic American Buildings Survey (HABS), based on a proposal by Charles E. Peterson, Park Service landscape architect. It was founded as a make-work program for architects, draftsmen and photographers left jobless by the Great Depression. Guided by field instructions from Washington, D.C., the first recorders were tasked with documenting a representative sampling of America's architectural heritage. After 70 years, there is now an archive of historic architecture. HABS provided a database of primary source material for the then fledgling historic preservation movement.
