|•Today NARA holds in the National Archives of the United
States and the Presidential Libraries an estimated 4 billion records
nationwide. The archives consist of
the permanently valuable records generated in all three branches of the
Federal Government, supplemented with donated documentary materials.
|•These records span this country’s entire experience,
across our history, the breadth of our nation, and our people. Not surprisingly, with the passage of time,
the medium of the records of the United States has become diverse in
format. While paper documents
predominate, NARA holds enormous numbers of reels of motion picture film;
maps, charts and architectural drawings; sound and video recordings; aerial
photographs; still pictures and posters; and computer data files. It is the last, the computer data sets, the
electronic records, that is the fastest growing record keeping medium in the
United States and elsewhere in the world, as well in most of your
institutions as well.
