I think it is worth noting that Richard P. Gabriel wrote the forward to the book in question, and he quotes Guy L. Steele in that forward -- from the paper that you are suggesting the author might like.
I did not think about it too much to be honest, I just knew that article and thought that he would really like it if he had not read it. But I can imagine somebody writing a book on the history of Lisp has already read probably all articles around on the topic.
I just did not think about it for too long.
