Thoroughly revised and expanded, this guide to the reference literature is the only up-to-date guide in the field and is by far the most extensively annotated. It covers all areas of Western and Eastern philosophy, emphasizing recent English-language publications but including some older and foreign-language sources. More than 450 reference works, about a third of them new to this edition, are listed, described, and often evaluated. Special chapters cover core periodicals and major organizations and research centers. Designed as an aid in reference work and collection development for librarians, this book will also be of interest to theologians, professional philosophers, philosophy instructors, and philosophy students.
