The David Montgomery Award is given annually by the OAH with co-sponsorship by the Labor and Working-Class History Association (LAWCHA) for the best book on a topic in American labor and working-class history. The award is given in recognition of David Montgomery's crucial role in pioneering new approaches to the study of working people and their history. Eligible works shall be written in English and deal with United States history in significant ways but may include comparative or transnational studies that fall within these guidelines. Each entry must be published during the period January 1, 2025, through December 31, 2025. One copy of each entry, clearly labeled "2026 David Montgomery Award Entry," must be mailed directly to the committee members. Bound page proofs may be used for books to be published after October 1, 2025, through December 31, 2025. If a bound page proof is submitted, a bound copy of the book must also be sent to each committee member and postmarked no later than January 7, 2026. While it is strongly encouraged that authors work with their publisher to coordinate submission for OAH prizes, OAH members are now able to self-nominate their works. Current OAH members who wish to self-nominate their book should write to OAH no later than three weeks before the deadline. Please include your name, the title of your work, and publisher information (please note self-published works remain ineligible). OAH staff will verify eligibility and provide further instructions. Please visit the award's website or contact the Organization of American Historians for more information.
