Book excerpt: This text provides an overview of major critical theorists from across disciplines—including the humanities, social sciences, and education—that discusses the importance of these critical perspectives for the advancement of LIS research and scholarship. The practical application of library and information science is based upon 75 years of critical theory and thought. Therefore, it is essential for students and faculty in LIS to be familiar with the work of a wide range of critical theorists. The aim of Critical Theory for Library and Information Science: Exploring the Social from Across the Disciplines is to provide a comprehensive introduction to the critical theorists important to the LIS audience, and to give insights into how such theory can be incorporated into actual LIS research and practice. This book consists of chapters on individual critical theorists ranging from Aglietta to Habermas to Spivak, written by an international group of library and information science scholars. Each chapter provides an overview of the theoretical stance and contributions of the theorist, as well as relevant critical commentary. This book will be particularly valuable as a reference text of core readings for those pursuing doctoral or masters level degrees in LIS.
