Noontime Rally In Downtown Philadelphia, August 1973

Dick Swanson was one of the many photojournalists to contribute to the Environmental Protection Agency's Documerica project in the early 1970s. Swanson's photography has an urban focus, particularly in the city of Philadelphia. The U.S. National Archives was established in 1934 by President Franklin Roosevelt, but its major holdings date back to 1775. The National Archives keeps only those Federal records that are judged to have continuing value -- about 2 to 5 percent of those generated in any given year. By now, they add up to a formidable number, diverse in form as well as in content. In addition to the photographs and graphic images described above, there are approximately 9 billion pages of textual records; 7.2 million maps, charts, and architectural drawings; billions of machine-readable data sets; and more than 365,000 reels of film and 110,000 videotapes. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.
