Meringolo (2004) compares academic and public history. Unlike academic history, public history is typically a collaborative effort, does not necessarily rely on primary research, is more democratic in participation, and does not aspire to absolute "scientific" objectivity. Historical museums, documentary editing, heritage movements and historical preservation are considered public history. Though activities now associated with public history originated in the AHA, these activities separated out in the 1930s due to differences in methodology, focus, and purpose. The foundations of public history were laid on the middle ground between academic history and the public audience by National Park Service administrators during the 1920s-30s.
