Throughout the long history of the United States, presidential records have some of the most diverse preservation of any of the United States' government documents. Presidential records were not the property of the federal government until the Presidential Records Act of 1978.
Presidential materials have seen wide duplication and distribution through a variety of formats: bound volumes, microfilm, photocopies, and now digitization. Collections may be populated with original manuscripts, copies, duplicates, or have substantive gaps. Digital collections are not all-encompassing.
This guide will help you access resources and institutions that provide access to presidential records.
Below are some general links that will orient you to the systems of preservation and access to presidential records. The guide's other tabs offer direct links to archival and digital collections for each American president.
