Having worked in the Ford and Reagan Presidential Papers, it’s worth noting that these are ONLY the official papers of the presidential administration. They do not include anything before taking office or after leaving office.
In addition, the papers of subordinates that are NOT policy related-—unless specific direct copies are made—reside at private collections in other libraries. For example, “Judge” William Clark, Reagan’s key advisor for yrars, has his papers at the Hoover Institution.
Yep. Things like his transcripts and birth certificate are not allowed to be unsealed by anyone other than the person they pertain to.
