*Subject:* [PCCLIST] 260 to 264 field conversion in RDA bibliographic
records in WorldCat

OCLC is beginning to convert 260 fields in RDA bibliographic records in
WorldCat to 264 fields.  Initial conversion will include the
straightforward cases, where 260 can easily be converted to 264 for a
publication statement.  Example:


260    $a London : $b Macmillan Education Limited, $c [1972]

*After Conversion*

264  1 $a London : $b Macmillan Education Limited, $c [1972]

Once the straightforward cases are complete, we will look at how to update
more complex cases.

Background: RDA cataloging instructions were used to create RDA
bibliographic records (coded 040 $e rda) prior to implementation of the
MARC field 264.  Since 264 was implemented in 2012, use of 264 fields
instead of the 260 field is preferred for RDA publication data.  Because of
that gap in time, there are about 1.5 million RDA records in WorldCat with
a 260 field instead of 264 fields.  Converting 260 to 264 will make the
data more consistent, and will facilitate conversion to future data

The January 2018 AskQC office hours (slides and Q&A available at announced plans for this.  For more information,
please view those slides and look at the summary and questions from that
