046 Special Coded Dates (NR) (Variable Data Field)
Field 046 contains 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 or incorrect dates.
When field 046 is used for B.C. dates, 008/06
is set to code b (No dates given; B.C. dates involved) and each character position in fields 008/07-10
and 008/11-14
contains a # (blank
).
When field 046 is used for incorrect dates, field 008/06 is coded for the type of corrected date and fields 008/07-10 and 008/11-14 contain correct dates.
In field 046, if subfields $b-$e contain a date that is less than four digits in length, it is not right justified and unused positions do not contain zeros.
The National level record requirement for this field is Optional.
Field 046 is NOT repeatable .
Guidelines for applying content designators:
The 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. Note that 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.
Single part and multipart items complete in one year | Collections and multipart items complete in more than one year |
r Reissue and original date | i Inclusive dates |
s Single date | k Bulk dates |
p Distribution and production dates | r Reissue and original dates |
t Publication and copyright dates | m Multiple dates |
x Incorrect dates | t Publication and copyright dates |
q Questionable date | x Incorrect dates |
n Unknown date | n Unknown date |

Subfield $a - Type of date code
Code c - Actual date and copyright date (BK CF MP MU VM) [obsolete]: Prior to the definition of code t (Publication date and copyright date) in 1995, code c was used. The use of code c for publication date and copyright date was made obsolete to provide for only one definition of code c (Serial item currently published) for use in 008/06 (Type of date/Publication status).
In 1999, field 046 was renamed from Type of Date Code, Date 1, Date 2 (B.C. Dates) to Special Coded Dates.
