Field definition and scope:

Field 504 contains a note indicating the presence of a bibliography(ies), discography(ies), filmography(ies), and/or other bibliographic references in an item.  It may also indicate the presence of a bibliography, etc. in accompanying material that is described in the record.  For multipart items, including serials, the note may pertain to all parts or to a single part or issue.

Notes referring to tables of cases, statutes, and regulations are not recorded in this field.  They are recorded in field 500 (General Note).  When the presence of an index is also mentioned in a bibliography note, field 504 is used.  If a note mentions contents in addition to the bibliography, and the bibliography is not deemed sufficiently extensive to warrant a separate note, the note is recorded in field 500 (General Note).  In cases of doubt as to whether the note is bibliographical or not, field 504 is used rather than field 500 (General Note).

The National level record requirement for this field is Optional.

Field 504 is repeatable.
