Content Media Carrier Type : LC-PCC Best Practices Guidelines
“If a resource includes multiple components (e.g., a volume and CD, with text, maps, and spoken word), you must describe all, using multiple 33X fields for Content, Media, and Carrier Type.”
Not necessarily. You must record the predominant term for each 33X field. If you wish to record additional fields, you may. Remember that each term is from a controlled vocabulary.
