Grant Hammond, a long-time associate of Boyd’s and the author of The Mind of War, John Boyd and American Security (Smithsonian Press, 2001), has published a new edition of Boyd’s Discourse on Winning and Losing. You can download it from Air University via a link on the Articles page.
Grant has included a new Introduction, along with an Afterword, index and an Appendix. You can access further information on some of the concepts via QR codes sprinkled throughout the text.
This is a major effort and makes a significant contribution to understanding John’s work. I strongly encourage all readers to download it.
If you’d prefer a hard copy, you can order one free of charge from Air University Press: http://www.airunioversity.af.mil/AUPress/
By the way, if you’re wondering what happened to Boyd’s last briefing, The Essence of Winning and Losing, Grant includes the material from it in the Appendix.
