Information literacy research is growing in importance, as evidenced by the steady increase in dissertations and research papers in this area. However, significant theoretical gaps remain. Information Literacy Through Theory provides an approachable introduction to theory development and use within information literacy research. It provides a space for key theorists in the field to discuss, interrogate and reflect on the applicability of theory within information literacy research, as well as the implications for this work within a variety of contexts. Each chapter considers a particular theory as its focal point, from information literacy and the social to information literacy through an equity mindset, and unpacks what assumptions the theory makes about key concepts and the ways in which the theory enables or constrains our understanding of information literacy. This book will provide a focal point for researchers, practitioners and students interested in the creation and advancement of conceptually rich information literacy research and practice.
