If this book has scripts and scene descriptions presented like in Sesame Street Unpaved, I think that more fan favorites shoudl get their own sections. A two-page spread of Harvey Kneeslaper sketches would be nice, as would a big section on Forgetful Jones. Back when Unpaved was released I was surprised that Guy Smiley got a big section in the sketches chapter but Baby Bear and Rosita only had small sections in the "More Mupets" section of the characters chapter. I was surprised that Guy Smiley wasn't in the "whatever happened to...?" section (in fact, none of Jim Henson's characters were there).
If sketches are grouped by character sections, then the Prairie Dawn section should at least have info on her pageants (it's odd that her two-page section in Unpaved didn't represent any pageants at all). I also found it odd that the book mentioned Kermit and Grover being best friends but didn't include any scripts or sketch descriptions of any of the sketches that Kermit and Grover appeared in together. In fact, the only time they are shown together in the book is in the two-page spread listing the Muppet performers and their characters, and even there they don't appear on the same page. In fact, I think the Kermit section focused too much on his news sketches. Only one non-news Kermit sketchw as included in that section (though others were in other parts of the book).
Of course, what would be better than all that would be a section that includes epsidoe guides for the various recurring sketches, in whatever Sesame Workshop considers the official order to be.
One thing that's odd about Unpaved is that Pinball Number Count wasn't represented at all. No lyrics (though the lyrics are just "1,2,3, 4,5,6,7,8,9, 10, 11,12), no mention, no images. I bet this one will, though. Sesame Workshop seems to be giving those sketches a lot of attention sicne the 35th anniversary (maybe not on the show itself, but elsewhere).
