Higher Education Outcomes Assessment for the Twenty-First Century ed. by Peter Hernon, Robert E. Dugan, and Candy Schwartz (review)

value of digital libraries, including how perceptions of value have changed, in ways that should aid planning future library services, spaces, and expectations in the networked environment. This discussion flows into a look at the origins and fast-moving nature of the social web, sometimes called Web 2.0, which focuses on user-generated content, networking, and social interaction. Calhoun describes digital libraries’ new role on the social web and raises the possibility of digital libraries as social platforms. She introduces a visual framework that attempts to bring some coherence to the many confusing elements of digital libraries’ evolution toward the social web and discusses the social web’s impact on scholarship. Calhoun ends the chapter by pointing out that libraries have traditionally been collection-centered, with core values different from the social web’s values of engagement and participation. Looking to the future in her final chapter, Calhoun writes, “Most digital libraries continue to operate from a traditional, collections-centered service model. Change will be difficult, especially in the realm of scholarly practices and norms, where the roots of tradition are deep.” (p. 256) She raises the need to rethink what libraries and digital libraries should and can do for society and concludes that “emulating the creativity and pioneering spirit of digital libraries’ first 20 years is the starting point for creating the next grand vision for libraries’ digital future.” (p. 256) Exploring Digital Libraries is a thorough examination of the past, present, and future prospects of digital libraries, and I recommend it to students, scholars, and practicing librarians.
