For decades, we have been told we live in the "information age"-a time when disruptive technological advancement has reshaped the categories and social uses of knowledge and when quantitative assessment is increasingly privileged. Such methodologies and concepts of information are usually considered the provenance of the natural and social sciences, which present them as politically and philosophically neutral. Yet the humanities should and do play an important role in interpreting and critiquing the historical, cultural, and conceptual nature of information. This book is one of two companion volumes that explore theories and histories of information from a humanistic perspective. They consider information as a long-standing feature of social, cultural, and conceptual management, a matter of social practice, and a fundamental challenge for the humanities today. Bringing together essays by prominent critics, Information: Keywords highlights the humanistic nature of information practices and concepts by thinking through key terms. It describes and anticipates directions for how the humanities can contribute to our understanding of information from a range of theoretical, historical, and global perspectives. Together with Information: A Reader, it sets forth a major humanistic vision of the concept of information.
