A moving image work may have one or more sets of elements, which in turn may be composed of one or more units.  These sets of elements must be described accurately and briefly, drawing together component parts of negatives, master positives, sound tracks, videocassettes, etc., and providing a quick method for comparing each set.  In this manual, this interrelationship among the sets of elements is expressed by providing a separate line of physical description for each set arranged in a standardized manner.  See Chapter 5.
