The story here is about how Eisenhower's book "Crusade in Europe" and the US Supreme Court Case involving this book have substantially changed and affected US Copyright Laws. The relevant decision by Justice Antonin Scalia is: Dastar Corp. v. Twentieth Century Fox Film Corp., 539 US 23 (2003). There is also a US Court of Appeals decision: Twentieth Century Fox Film Corp. v. Entertainment Distributing, 429 F.3d 869 (9th Cir. 2005).
This book is a reprint of both decisions plus Exhibit A (the book), because it comes up so often in publishing or reprinting old books.
