Thanks. Are RIFs used at the National Archives? Or is it just the Mary Ferrel wesbite?
From the Ferrell site: "The National Archives attached a form page to most documents declassified in the 1990s, with fields for titles, subjects, originating agency, from and to, declassification status, and more. When viewing such a document, this is usually the first page. You can also use the "RIF Form" tab to view the data as a form. "
So it's a NARA format. If I recall, you can do three (five?) searches for free at the Ferrell site. You are limited unless you are a member. It's now $35.00 for regular membership.
