Date of item information that cannot be recorded in 008/06-14 (Type of date/Publication status, Date 1, Date 2) because such information involves one or more Before Common Era (B.C.) dates, incorrect dates, dates when resources have been modified or created, and date spans when resources are valid. When field 046 is used for B.C. dates, 008/06 is set to code b (No date given; B.C. date involved) and field 008/07-10 and 008/11-14 contain blanks (####). When field 046 is used for incorrect dates, field 008/06 is coded for the type of corrected data and field 008/07-10 and 008/11-14 contain correct dates.
Guidelines on how to transcribe a date in subfields $b, $c, $d, and $e are generally the same as those specified under 008/06 (Type of date/Publication status), 008/07-10 (Date 1) and 008/11-14 (Date 2), except that incorrect dates and B.C. dates may be recorded only in field 046.
Precedence of codes (monographic items) - When more than one code applies to the date(s) related to a bibliographic item, use the table below to determine the appropriate code to use. The codes listed in each column are in precedence order, with codes listed first taking precedence over codes listed subsequently. The left column covers single part items and multipart items completed in one year. The right column covers multipart items for which a span of dates is required.
