Whoa there with the congrats on "The Dancing Chain". It is chock full of errors and was not written by Frank Berto, but rather by three authors each writing their own part. The part compiled by Frank Berto is the part where I found the most errors, even though being the newest part it should have been the easiest to get right. I was gifted a copy of the first edition by one of the co-authors. I then bought a second edition hoping that the numerous glaring errors had been corrected, but found very little to have been modified. I therefore sold it onwards to somebody else. I also found it in very poor taste that the name of one of the co-authors was removed from the second edition after his death. Notwithstanding the many errors, it is still a noteworthy book and valuable to the average collector. Just don't put too much value in everything that is said. I rate "The Dancing Chain" as head and shoulders above the Campagnolo fluff piece that was put together by two rank amateurs and journalistic thieves. The pitiful accuracy of the Campagnolo book is all the more glaring because the authors are supposedly "true" journalists (In Italy, there is an "ordine dei giornalisti" or Order of Journalists, which requires certification and examination for admission.) I guess they both missed the parts relating to quoting your sources and respecting the work of others.
