Theories stating that plays attributed to Shakespeare were in fact written by other authors have existed for more than 200 years; some theories have been ridiculed and reviled while some have gained growing popular and scholarly support. The history of the Shakespeare controversy is presented in this revised edition of the 1992 work, with much new information and three additional chapters. Part I documents and critically assesses the most important theories on the authorship question. Part II is an annotated bibliography, arranged chronologically, of the many works that deal with the controversy from its vague beginnings to the present.
