The library maintains the world’s largest collection of books, manuals and essays written about the PR field since the late 1800s. Many of them are rare first editions by Edward Bernays, Ivy Lee, John Hill, Philip Lesly and Doris Fleischman. 

Visitors have access to dozens of books (many of them from Bernays’s own library) covering such subjects as psychology, social psychology, news media and political history. Authors include such well-regarded thinkers as Walter Lippman, Gustave LeBon, Everett Martin and Alfred Trotter.

The museum also has dozens of video taped interviews with influential leaders of the PR field, among them Daniel Edelman, Harold Burson, David Finn, Edward Bernays, Herb Schmertz, Muriel Fox and Ed Block.
