"Wow. What a book and what an undertaking. This should be a must-read for the most exacting fly fisherman. I would guess that it will be one of the most important reference volumes ever written. It should be read and re-read many times."--Ed Shenk, author of Ed Shenk's Fly Rod Trouting • Strategies for fooling tough fish in all types of environs, from tailwaters to spring creeks to Gaspe salmon streams • Breathtaking photos from the top streams around the world • Hundreds of innovative fly patterns with recipes and notes

This book retains the accessibility of the previous editions while incorporating the latest research findings, and updated organizational applications of the principles of I-O psychology. The scientist-practitioner model continues to be used as the philosophical cornerstone of the textbook. The writing continues to be topical, readable, and interesting. Furthermore, the text includes additional consideration of technological change and the concomitant change in the reality of work, as well as keeps and reinforces the systems approach whenever possible, stressing the interplay among different I-O psychology variables and constructs.
