046 - Special Coded Dates (R)


MARC 21 Bibliographic - concise
November 2016

Date of item information that either 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.E.) dates, incorrect dates, dates when resources have been modified or created, and date spans when resources are valid, or is recorded here in addition to appearing in 008/06-14. When field 046 is used for B.C.E. dates, 008/06 is set to code b (No date given; B.C.E. 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.
