Preservation Microfilming at the National Archives

Preservation is the first responsibility of any archives. As archivists search for newer, more effective techniques and technologies for preserving the archival record, we must not—indeed, we cannot—lose sight of two overwhelming archival realities. One is the enormous volume of the records held by archival institutions. The National Archives and Records Administration (NARA) alone hold billions of paper documents and millions of photographs, films, magnetic recordings, and so forth—very, very few of which are exquisite treasures, but all of which must be preserved indefinitely, in one form or another. The second inescapable reality is that archival institutions are rarely near the top of anyone's list of budget priorities. (Are there any dissenters?) Financial resources for preservation, or any other archival program, are very limited.
