Subtitle

The secondary name in the formal title of the item, usually indicated by punctuation
such as a colon ( : ) or brackets ( [ ] ).

(Formal titles are the specific bibliographic titles written on individual items, such as the title of a movie or book. When transcribing a formal subtitle, enter any dates exactly as they appear.)

Enter the formal subtitle exactly as it appears on the item. If the formal subtitle is incorrect or vague, enter a corrected version in Other Title. Variant or translated subtitles should also be entered in Other Title.

Use initial capital letters. Do not end a subtitle with a period. Do not enter a colon after the title or before the subtitle. A colon may be added by the system as part of the display.

If Subtitle uses an acronym that is not defined in either Title or Scope and Content Note, define the acronym the first time that it is used in Subtitle.
