It's interesting how many chapters focus more on certain projects than others, while also talking about what else was going on at the time, and those projects that do get most of the focus in a given chapter still get talked about a bit in future chapters (mainly TV shows that were still in production), though it seems Sesame Street isn't brought up as much in the same way after the Sesame Street chapter.
Sesame Street is brought up every now and then after its own chapter, and there are parts that talk about Julie on Sesame Street and 20 and Still Counting. But considering that, one thing that surprised me is that, in a later chapter, it briefly acknowledges when work was done on Barkly, without really talking more about it. I think Barkley is the only Sesame Street character whose development was mentioned outside of the Sesame Street chapter (Elmo doesn't even get such treatment, though it does at one point mention that Richard Hunt handed over - or actually threw over - the role to Kevin Clash).
I wonder how many of the quotes were from interviews conducted for this book and how many were taken from other sources. I've read that Jane Henson was interviewed, I assume most of Jim's children's were interviewed, and I think Frank Oz was interviewed for this. But many of the quotes are quotes I've already read in the past. I assume most of Bernie Brillstein's quotes come from his autobiography, and Jerry Juhl's quotes must have come from somewhere (I've read that this book has been in the works for awhile, but I doubt it was in the works as far back as when Juhl was alive). In the section that sources quotes, it seems like for the most part it only lists the names of those being quoted, as opposed to listing where the quotes come from.
