The well-received first edition of the Encyclopedia of Industrial and Organizational Psychology (2007, 2 vols) established itself in the academic library market as a landmark reference that presents a thorough overview of this cross-disciplinary field for students, researchers, and professionals in the areas of psychology, business, management, and human resources. Nearly ten years later, SAGE presents a thorough revision that both updates current entries and expands the overall coverage, adding approximately 200 new articles, expanding from two volumes to four. Examining key themes and topics from within this dynamic and expanding field of psychology, this work offers a truly cross-cultural and global perspective.
