"An indispensable handbook that will be kept close at hand—used, reached for, and above all really read by those seeking a conceptual framework through which to understand the practicalities of grappling with the complex new reality of digital objects. Opening up the most theoretically sophisticated body of research in digital platforms to an entirely new audience while simultaneously equipping that audience with the conceptual background they need to function as experts in today's information environment, Owens's book is a practical, even-handed, and clear-eyed walkthrough of day-to-day situations. I expect it will be widely adopted in library and information science courses."
