Jay Weitz of OCLC says:
"The codes "isbdcontent" and "isbdmedia" are Genre/Form Code and Term
Source Codes that were announced by the Library of Congress in its
2013 February 22 Technical Notice
(http://www.loc.gov/marc/relators/tn130222src.html). They are part of
the upcoming OCLC-MARC Update on which we are furiously working. As
is always the case with such new codes, the Technical Notice also
says: 'The codes should not be used in exchange records until 60 days
after the date of this notice to provide implementers time to include
newly-defined codes in any validation tables.'"
So they should be acceptable by the time SLC starts loading 337 $a
electronic$2isbdmedia to OCLC in September.
