"Robert Post’s study of the evolution of America’s premier museum is authoritative, thorough, and engagingly written by a curatorial insider with a critical perspective. His judgment of Smithsonian controversies during the past generation is reliable and well informed, especially those concerning the history of technology. This is institutional history in the very best sense because it highlights the role of individuals as well as ideas. We also gain insight into the museum’s place in national politics. A most enlightening project."
