Beginning in the 1930s during the Great Depression, some libraries were meticulously measured, documented and photographed under the Historic American Buildings Survey (HABS) program of the National Park Service. This was part of an effort to record and preserve significant buildings.. Other documentation has been collected by local historical societies. In 1935, the centennial of Carnegie's birth, a copy of the portrait of him originally painted by F. Luis Mora was given to libraries which he had helped fund. Many of the Carnegie libraries in the United States, whatever their current uses, have been recognized by listing on the National Register of Historic Places. The first, the Carnegie Library in Braddock, Pennsylvania, was designated as a National Historic Landmark in March 2012. Some Carnegie Libraries, have been replaced in name with that of city libraries such as the Epiphany library in New York City.
