Adaptations and Promptbooks: When the London theaters reopened in the 1660s, adaptations of Shakespeare's plays were often presented on the stage. Sometimes the title, the setting and the dialogue were altered and only the outline of the action remained, as in Poole's Hamlet Travestie (1810) an adaptation of Hamlet. More often the title and much of Shakespeare's language was retained, but the adapted text made cuts, additions, changes in wording and offered alternative endings. Since virtually all performed texts differ from printed texts, the boundary between an adapted text and a text marked with cuts and changes for performance is not an absolute one. A promptbook is a text, usually printed, marked for performance. In addition to cuts and additions, promptbooks often include a wealth of information about how a play was acted, and sometimes include sketches of sets and other pictorial material.
