Michael Jensen has been at the interface between digital technologies and scholarly/academic publishing since the late 1980s. From 1998 to 2007, he was Director of Publishing Technologies for the National Academies Press, which makes more than 3700 books (more than 650,000 pages) from the National Academy of Sciences, the National Academy of Engineering, the Institute of Medicine, and the National Research Council fully browsable and searchable online for free (http://www.nap.edu). This site receives more than 1.5 million visitors per month, and boasts of some of the most advanced search and discovery tools available on any publisher’s site, most of which were initially developed by Mr. Jensen.
