is available in a new, free online e-book by Adrian Weiss, W0RSP.
It is entitled, The Five-Watt QRP Movement in the US, 1968-1981, and is available by clicking on the title. The hyperlink will take you right where you need to go.
I have already downloaded it and will send it to my Kindle, so that I can read it without being tied to the computer. The history of QRP and how 5 Watts came to be the "definition" of QRP is intriguing to me. My very first membership certificate explained that QRP was considered to be 100 Watts or less. As a Novice, pushing out 75 Watts max with my Drake 2-NT was a natural fit, so I joined QRP-ARCI way back when in 1979.
I never got involved in the 100 Watt vs. 5 Watt debate; but had no problem with the final decision. Operating with low power always fascinated me and I had lots of fun and good times with it, throughout my earlier Ham career. Going strictly QRP back in 2003 is something I have seldom regretted. I'd be lying if I told you there weren't times that I wished I had 100 Watts in order to help bust through a pileup in order to snag a new DX entity. But limiting your self to lower power helps to reinforce discipline and knowing your limits and capabilities. Good life lessons.
