Definition

Date of item information that cannot be recorded in DtSt and Dates because B.C. dates, incorrect dates, dates when resources have been modified or created, or date spans when resources are valid are involved.

If you use field 046 for B.C. dates, enter code b (B.C. date) in DtSt and blanks in Dates. If you use field 046 for incorrect dates, enter the type of corrected dates codes in DtSt and the corrected dates in Dates.

Guidelines

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 lists below to determine the appropriate code to use. In each list, codes listed first take precedence over codes listed subsequently. The first list covers single part items and multipart items completed in one year. The second list covers multipart items for which a span of dates is required.

Single part/multipart items complete in one year

r Reissue and original date
s Single date
p Distribution and production dates
t Publication and copyright dates
x Incorrect dates
q Questionable date
n Unknown date


Collections/multipart items complete in more than one year

i Inclusive dates
k Bulk dates
r Reissue and original date
m Multiple dates
t Publication and copyright dates
x Incorrect dates
n Unknown date
