I would be grateful for help in where to find the value of this item. It has a hard cover with gold emboss printing. The cutting continuity contains the full script and also the camera movements. My understanding, which is limited, this would have been used by the director, producer or camera men.

To be honest paper items like this are not my kind of thing.
I would suggest asking someone like Moviegoods.com or Profilesinhistory.com what they think.
