The book follows the show chronologically, with chapter headings broken into chunks of time, such as “Exordium: 1975-1976” and “Heyday: 1976-1980”. It's an oral history, in that the majority of the book is in the words of the people interviewed, from cast members and writers to agents, producers and executives. And it's all incredibly fascinating. In the chapters from the later years, there were some cast members I'd never heard of, and a lot of cast members who I am familiar with but had not known were in the cast (Julia Louis-Dreyfus!). The book is long, 600 pages not counting the index in the back, and only goes up to the 2002-2003 season. Looking at the different editions on Goodreads, another updated edition was published in 2014, with “over more than 100 pages of new material”, and I would love to find a copy of that edition just to read those additional pages.
