Modern prompt books will tend to be constructed using binders with multiple tab dividers, with the page of the production attached to a larger sheet of paper to provide more margin space for taking notes. Markings to the script (for cues, notes, etc.) are typically done in pencil, and either in the margins or on the blank side of the back of the opposing page. In situations where there are multiple stage managers or assistants, it is not uncommon for many copies of the prompt book to exist. Generally a lead stage manager will keep the master book, which is then copied by assistants on a nightly basis to account for any new information inserted during rehearsals, productions, and meetings. While all prompt books will contain some of the same basic information (script, cast list, contact information, set drawings, etc.), there is no official standard, and individual stage managers will determine the best way of keeping books for themselves and the productions they manage. While
Actors' Equity Association, the union governing professional stage managers in the
United States, does not publish any official pragma for a prompt book, such practices are often covered as part of college curricula, and many books exist on the subject. ==History==
