"Making it on Broadway" seemed way too whiny. I understand many of the actors were trying to make a point about the difficulties of life in the theater, but after a while, I got sick of reading about it.
My personal favs include one no one here has mentioned yet, and I am surprised. It's called "Broadway Stories" by Marty Bell, and they interview actors, producers,directors and more from shows such as City of Angels, Guys and Dolls, Jelly's Last Jam and so on. It's a great book with lots of backstage stories from the mid 1990's era of theater.
There's also a great coffee table book of photos called Broadway Day and Night. It was produced around the same timeframe, and it's beautifully photographed, with side stories from all the Broadway names you would expect.
