The Computer History Museum Prize is awarded to the author of an outstanding book in the history of computing broadly conceived, published during the prior three years. The prize of $1,000 is awarded by SIGCIS, the Special Interest Group for Computers, Information and Society. SIGCIS is part of the Society for the History of Technology. In 2012 the prize was endowed in perpetuity through a generous bequest from the estate of Paul Baran, a legendary computer innovator and entrepreneur best known for his work to develop and promote the packet switching approach on which modern networks are built. Baran was a longtime supporter of work on the history of information technology and named the prize to celebrate the contributions of the Computer History Museum to that field. *2018 Call for Submission* Books published in 2015-2017 are eligible for the 2018 award.
