The preferred source of information for moving image materials is the work itself (i.e., main title, beginning and end credits, intertitles, spoken credits).

If information is not available from the preferred source, take it from secondary sources (e.g., leader, containers, accompanying material, unpublished documentation, standard and specialized reference tools, telephone calls).

If information found on the preferred source is judged to be completely incorrect, also take information from other sources.

Information is not bracketed with the following exceptions.  When information is judged to be probable, enclose that information in brackets.  If it is judged to be questionable, include a question mark in the brackets.  If information is supplied by the cataloger, i.e., it is neither from the work nor another source, enclose it in brackets.  When the rules refer to brackets, always use square brackets.

Brackets are not required for most notes.  However, they may be used for credits, participants or performers, and contents notes.  See 7B5, 7B6, and 7B28.

For guidance on citing sources of information, see 7B and 7B25.  A note is not required to explain cataloger-supplied information.
