Welcome to the forum.
I am familiar with your writings on at least one other forum (USMS) and am a subscriber to your youtube channel. I find your stuff on butterfly particularly valuable.
Terry's blue and yellow book was the key to enabling me to be able to swim more than one 25m length of crawl and I think of it as the best book ever written on swimming, although I am also very devoted to certain others, such as Swimming the American Crawl by Johnny Weismueller, Competitive Swimming and Diving by David Armbruster and The Science of Swimming by James Counsilman. Thanks to Terry I was also made acquainted with the work of Howard Firby and managed to transcribe a lot of Firby on Swimming, which I still turn to often. It is now out of print and hard to come by. I would love to find an affordable copy of the book by William Bachrach, Weissmueller's coach, but the only one I have seen advertised was offered as 600 dollars. I have a little pamphlet published by Kellogs of cornflake fame in 1935 that I suspect of being largely the work of Bachrach but this is just a guess. However, somewhat as some Roman Consul said to Saint Paul the Apostle, '"much reading hath made thee mad", and my stroke still needs a lot of work.
You are certainly welcome here as far as I'm concerned. I think you would also enjoy some of Terry's later writings, because his concept of the freestyle stroke has changed somewhat since the blue and yellow book. I also think you might enjoy the DVDs and of course there is now a wealth of stuff on youtube.
We will soon be able to watch video of the world's best at the Olympics and with a bit of luck some of it will find its way to youtube, although I get the impression that copyright is going to be strongly enforced.
