I'm a librarian, researcher, policy maker, and educator working on digital infrastructure for libraries. I'm the first Head of Digital Content Management for Library Services at the Library of Congress. I teach graduate seminars in digital history for American University’s History Department and graduate seminars and digital preservation for the University of Maryland’s College of Information, where I'm also a Research Affiliate with the Digital Curation Innovation Center. I'm the author of three books, the most recent of which, The Theory and Craft of Digital Preservation, is in press with Johns Hopkins University Press.
