Examples from RDA Basics:

The following are some examples of how these three fields will look for different resources. A basic book would be coded in this way:

336 ## text $2 rdacontent
337 ## unmediated $2 rdamedia
338 ## volume $2 rdacarrier

The “$2” subfields are mandatory. A DVD would look like this:

336 ## two-dimensional moving image $2 rdacontent
337 ## video $2 rdamedia
338 ## videodisc $2 rdacarrier

An audiobook on CD would look like this:

336 ## spoken word $2 rdacontent
337 ## audio $2 rdamedia
338 ## audio disc $2 rdacarrier

And a Web site would look like this:

336 ## text $2 rdacontent
337 ## computer $2 rdamedia
338 ## online resource $2 rdacarrier
