From the editor's desk

Editor in Chief Jeffrey R. Yost announces the appointment of Dr. Lars Heide as the new editor in chief of the Annals, beginning in January 2012. A current member of the Annals editorial board, Heide has made strong contributions to the literature on the history of computing for more than two decades. This Annals issue includes an article on the basis and context of the Arpanet project as well as articles on the first half-century of the American key-set office machine trade (by Heide), the development of cash-dispensing machines in the UK, an examination of historical trends of electrical efficiency in computing, and the history of Swedish camera manufacturer Hasselblad's early and continuing work in digital imaging.
