The Mary Nickliss Prize in U.S. Women's and/or Gender History is given annually to an academic historian for "the most original" book in United States Women's and/or Gender History. The OAH defines "the most original" book as one that is a path-breaking work or that challenges and/or changes widely accepted scholarly interpretations in the field of U.S. Women's and/or Gender History. Each entry must be published during the calendar year preceding that in which the award is given, January 1, 2023 through December 31, 2023. One copy of each entry, clearly labeled "2024 Mary Nickliss 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 the committee members for the mailing address and provide title(s) you will submit for consideration so the committee can verify that all books have been received. Please visit the award's website for more information.
