The individuals and corporate bodies responsible for the major functions as recorded in the bibliographic record generally should be given added entries.  The major functions are the following:  production company, distributor, sponsor, director, producer, writer, cinematographer, editor, composer, participant and/or performer.  If there is more than one person or corporate body performing any of these functions, then added entries should be made for all of them.  If this would lead to what is deemed an excessive number of added entries, then only those considered significant should receive added entries.

For versions and editions, the above guidelines should be followed for those involved in the creation of the original work.  In addition, added entries for those persons and corporate bodies which made significant contributions to the creation of the version or edition should be made.  For example, an added entry could be made for the production company and producer of a videodisc version of a feature film which includes footage not used in the original release, an interview with the director, still photographs of storyboards, a trailer, and a short film on a related subject that was produced at the same time as the feature.
