The Pulitzer Prize for the most significant book on American history has been awarded each year since 1917, and is thus among the most traditional of the honours. Chronicle of the Pulitzer Prizes for History, the first supplement volume, documents the complete history of the development of the awards in this category from 1917 to 2005. The presentation is mainly based on primary sources from the Pulitzer Prize Office at the New York Columbia University. The most important sources are the confidential jury protocols, reproduced completely as facsimiles for the first time in this volume, and providing detailed information about each year's evaluation process.
