Most of the 540 pages are given over to alphabetic listing of characters and locations in the plays, actors, directors, theatre managers and critics from the late 16th century until the present. Then there are, among other things, technical terms to do with the theatre or with language and names such as Wagner, Zoffany, Arnold, Marlowe, whose work connects in any way with Shakespeare. There is no index but the book opens with a detailed account of the plays' dramatis personae, themes and associated names; and it ends with maps, a Royal family tree to help you pick your way through the history plays and a timeline giving a chronology of Shakespeare's life and works (and their reception). There are also suggestions for further reading. Each play gets several pages at the appropriate point in the alphabetical arrangement. The commentary includes a synopsis, textual information and some facts on the play's sources, along with an account of its stage and critical history and artistic features. The section about published editions and criticism of each play is useful too. Apocryphal plays such as The Merry Devil of Edmonton are mentioned more briefly.
The Oxford Companion to Shakespeare is an attractive book--with its A4 format, shiny paper and plenty of pictures--to browse through as well as use as a reference. --Susan Elkin
