The Ellis W. Hawley Prize is given annually by the Organization of American Historians to the author of the best book-length historical study of the political economy, politics, or institutions of the United States, in its domestic or international affairs, from the Civil War to the present. Eligible works are book-length historical studies written in English. Each entry must be published during the period January 1, 2023 through December 31, 2023. One copy of each entry, clearly labeled "2024 Ellis W. Hawley Prize Entry," must be mailed directly to the committee members listed in the award's website. If a book carries a copyright date that is different from the publication date, but the actual publication date falls during the correct time frame making it eligible, please include a letter of explanation from the publisher with each copy of the book sent to the committee members. Please contact committee members for mailing address and provide title(s) you will submit for consideration so the committee can verify that all books have been received.
