RDA-L readers, Thanks to Mark Ehlert for the correction to my earlier post. Here are the instructions he refers to. Curiously, 3.2.1.3 has a table, but 3.3.1.3 does not. 6.9.1.3 has a table and also a link from the sentence to the head of the table.
3.2.1.3 RecordingMedia Type: If none of the terms listed in table 3.1 apply to the carrier of the resource being described, record other. If the media type or types applicable to the resource being described cannot be readily ascertained, record unspecified. 3.3.1.3 RecordingCarrier Type: If none of the terms listed above apply to the carrier or carriers of the resource being described, record other. If the carrier type or types applicable to the resource being described cannot be readily ascertained, record unspecified. 6.9.1.3 RecordingContent Type If none of the terms listed in table 6.1 apply to the content of the resource being described, record other. If the content type applicable to the resource being described cannot be readily ascertained, record unspecified. - Ian
