RDA 3.3

RDA 3.3: CMC Processing

Content, Media, Carrier

To add 33X fields with the appropriate RDA Content, Media, and Carrier terms, the MARS 2.0 processing utilizes over 600 individual rules in order to properly map to the most correct set of 33X fields for the record. For instance, there are over 100 rules dedicated solely to electronic resources. If present, GMDs are used in the vetting process, as well as 006, 007, and 008 fixed field positions.

You can specify whether you would like to exclude any or all of the 33X fields from being generated as part of the mapping between 245 $h GMD and 33X Content, Media, and Carrier types.

$a term

 
 original record:
   LDR  02081cjm  2200517 a 4500
   007  sd fsngnnmmned
   245  $a Violin concerto $h [sound recording] :$b Piano quintet /$c Dvorak.
   300  $a 1 sound disc :$b digital ;$c 4 3/4 in.
 
 added 33X fields:
   336  $a performed music $2 rdacontent
   337  $a audio $2 rdamedia
   338  $a audio disc $2 rdacarrier

$b code

33X $b codes can also be added which can be similar in usage to relator codes, as far as being machine-actionable by your library system:

 
 added 33X fields:
   336  $a performed music $b prm $2 rdacontent
   337  $a audio $b s $2 rdamedia
   338  $a audio disc $b sd $2 rdacarrier

For each 33X field you may also choose whether to add a $a term, $b code, or both of these subfields. A subfield $2 will be added with the appropriate RDA term ($2 rdacontent, $2 rdamedia, $2 rdacarrier) If you would like to use another vocabulary of terms that can be identified in a $2 please contact your project manager.
