MARC 046 Special Coded Dates (Bibliographic)

Jump to: navigation, search

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 260ǂc, 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.
