Punctuation:  Use the period, space punctuation to separate the descriptive category from the descriptive phrase.  If a number is used between a descriptive category and a descriptive phrase, use the period, space to separate the descriptive category from the number, and the comma, space to separate the number from the descriptive phrase.

For works which may have had legitimate titles, use a descriptive category such as collection name, production company, genre, etc., as the first part of the supplied title.  When there is more than one work in the same descriptive category, use a number to distinguish them.  Use a descriptive phrase which may include the name of a cast member or production company, a genre, or other significant information as the next part of the supplied title.  Follow the descriptive phrase with the form term "unidentified works."

For works which may never have had legitimate titles, supply a descriptive phrase as the first part of the title proper.  Include important elements such as personalities, events, dates, places, subjects, etc., as they apply, in the descriptive phrase.  Follow the descriptive phrase with the appropriate form term.
