Reviews

"This unique text offers an attractive, reader-friendly layout, demonstrating concepts creatively with thought provoking color and b&w photos, illustrations, and images, many from art history. The volume is designed so that readers can jump from image to image and find the core ideas of the chapter. Sidebars of key ideas also increase the book's browsability. Employing a multidisciplinary approach to information architecture and the design of the new pervasive information spaces, the book draws on insights in diverse disciplines from cognitive psychology to cinema. Each chapter begins with a short story and concludes with case studies and a list of articles, books, movies, and videos. Part 1 surveys information architecture as both a field of practice and a research discipline. Part 2 illustrates five design principles, and Part 3 shows how to apply these principles with a real-life case study. Parts 2 and 3 include boxed contributions from international authors, researchers, and practitioners. Readers can access a companion web site and a blog."--Reference and Research Book News
