There is '''no required''' punctuation and style in the 670 field. There is some prescribed content (per the ''MARC 21 Authority Format'') and some suggested punctuation (see no. 2-4 of this FAQ). The 670 section in the Descriptive Cataloging Manual (DCM) Z1 supplement to the ''MARC 21 Authority Format'' states, '''"conventions in regard to punctuation and style ... are not prescriptive ... Punctuation and style need not be consistent from record to record as long as the information is clear and accurate."''' For historical purposes and because catalogers will continue to find NARs in the authority file which contain "old style" citations, the DCM Z1 shows varied examples. | There is '''no required''' punctuation and style in the 670 field.
