This book does give a modest but thorough description of each opera except Thespis and a recounting of each original production, the presentation of opening night performers, and a musical synopsis of major numbers. But there is more. What makes this book different than standard reference books covering the same material lies in the wealth of material Wilson used to embellish the book and the wealth of material which he had at his disposal. And use them he did, judiciously. Wilson added passages of dialogue, song lyrics, stage directions given in the libretti as they were published and performed during Gilbert's lifetime.
Some passages differ slightly from today's accepted standard.
The Pierpont Morgan Library lays claim to having the largest collection of Gilbert and Sullivan materials in the world, and the claim is supported by the wealth of fascinating facts con- cerning the two men and their works. In the back of the book is a two-columned chronology, covering three pages, of their accomplishments throughout their lifetimes. It is hard to believe that both men were so active creatively when working with or without each other. Of interest in this chronology was Richard D'Oyly Carte who, early in the writing and composing careers of Gilbert and Sullivan also displayed his own talents in writing and composing. In an added text, Wilson details the Pierpont Morgan Library's collection on Gilbert and Sullivan.
