The English National Opera Guides were originally conceived in partnership with the English National Opera and edited by Nicholas John, the ENO's dramaturg, who died tragically in an accident in the Alps. Most of the guides are devoted to a single opera, which is described in detail—with many articles that cover its history and information about the composer and his times. The complete libretto is included in both the original language and in a modern singing translation—except where the opera was written in English. Each has a thematic guide to the most important musical themes in musical notation and each guide is lavishly illustrated. They also contain a bibliography and a discography which is updated at each reprint. The ENO guides are widely regarded as the best series of their kind and excellent value.

These Opera Guides are ideal companions to the opera. They provide stimulating introductory articles together with the complete text of each opera in English and the original. Winton Dean relates how Otello came into being as much because of the persistence of Verdi's publisher as of the composer's lifelong passion for Shakespeare, and the collaboration of the brilliant poet Arrigo Boito. Benedict Sarnaker argues that this magnificent largescale opera rivals Shakespeare in intensity and profundity. William Weaver's lively review of Shakespeare on the Italian stage in the last century enables us to make a wholly fresh appraisal of Verdi's stature as a dramatist. The libretto itself is a masterpiece, and Andrew Porter has also translated the third-act revision which Verdi came to prefer and which has not been performed outside France before the 1981 ENO production.
