MARC 21 field 046 in the Bibliographic format contains date of item information that cannot be recorded in 008/06-14 (Type of date/Publication status, Date 1, Date 2). For our purposes, it will be used primarily when a transcribed date on an item is incorrect and has been corrected in the 260/264ǂc, whether because of unintentional errors, deliberate attempts to mislead, or the date is of an original resource when you are cataloging a reproduction. Note: MARC field 046 Special Coded Dates also exists in the authority format, but is defined differently.

ǂc Date 1 (C.E. date) 
ǂe Date 2 (C.E. date)

Policy and formulation

  • 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.
  • Hamnet indexes the 008 and the 046 dates in the staff modules and the opac. See http://hamnet.folger.edu/cgi-bin/Pwebrecon.cgi?BBID=180721
  • OCLC Connexion does not index the 008 dates when an 046 exists. See #22479058

Examples

Single part/multi-part items complete in single year with an incorrect date, complete the fixed fields for the corrected date, and add the incorrect date from the resource in field 046.
