The Mahoney Prize recognizes an outstanding article in the history of computing and information technology, broadly conceived. The Mahoney Prize commemorates the late Princeton scholar Michael S. Mahoney, whose profound contributions to the history of computing came from his many articles and book chapters. The prize consists of a $500 award and a certificate. For the 2018 prize, articles published in the preceding three years (2015, 2016, and 2017) are eligible for nomination. The Mahoney Prize is awarded by the Special Interest Group in Computers, Information, and Society (SIGCIS) and is presented during the annual meeting of our parent group, the Society for the History of Technology. The deadline for submission for the 2018 Mahoney Prize is *April 30, 2018*. To nominate an article, send an electronic copy to all three committee members using the email address below.
