{"value"=>"<p>The records of the Production Materials series (1958-1992) contain prompt books, light plots, ground plans, costume plots, set designs, electrics, prop running sheets, prop preset sheets, prop inventories, light cue sheets, and electrical layouts. Oversized materials such as light plots and ground plans were removed to the Oversized Materials series.</p> <p>The records reflect all physical aspects of the staging of a production. These materials should allow a researcher to properly reproduce a director's interpretation. The central functional item for each production in this series is the prompt book. The prompt book contains light cues, sound cues, and stage directions. Changes in script or a player's actions are written in the margins of a page or added as attachments to the script. A play that requires a lot of movement or contains a large cast will usually have a separate blocking script. A musical with dancing or fight sequences, such as <span class=\"title\">A Chorus Line</span> or <span class=\"title\">The Mystery of Edwin Drood</span>, may have several annotated scripts to complete the director's vision of the production. Other materials most often found represent the purely technical aspects of a production, such as lighting plots, costume plot, property information, ground plans, electrics and set designs. Related documents include prop running sheets, prop preset sheets, prop inventory, light cue sheets, and electrical layouts.</p> <p>The records range from <span class=\"title\">Twelfth Night</span> (1958) to <span class=\"title\">Fires in the Mirror</span> (1992). Some productions were meticulously documented such as <span class=\"title\">The Mystery of Edwin Drood</span> and <span class=\"title\">Fires in the Mirror</span>, while <span class=\"title\">Fishing</span> by Michael Weller contains only a script. The plays done before the mid-1970's are in general poorly documented. Success and scale may have been a factor in the preservation of production materials. Long-running or successful shows, such as <span class=\"title\">Runaways</span> and <span class=\"title\">For Colored Girls</span> have copious memoranda and production materials. Large productions, such as <span class=\"title\">Pirates of Penzance</span>, and other multi-venue productions (road companies, Broadway, and Mobile Theater) tend to be well documented.</p>"}
