So, in MARC terms, one would have LDR/06=g for "projected media" and 006/00=i for "nonmusical sound recording" to capture the essential content types of a movie-- "two dimensional moving image" and "spoken word"???? That's rather absurd when one steps back and looks at what is being proposed, and what is not even suggested by RDA, which reflects a lot of current categorization decisions for content types derived from AACR2 and MARC. I watch movies and read subtitles. I plan to watch the (nearly) silent movie "The Artist." Spoken Word is not a relevant content distinction that needs to be added for users to identify movies as movies. It's only at that very broad "identify" user task requirement that decisions about Content Type need to be made. The other details can be added as supplementary elements, useful for further selections (films with closed captioning, films dubbed or subtitled in a particular language, form/genre category for "silent films", etc.). In MARC, the equivalent to Content Types are captured by one predominant type in the LDR field, and other content types in 006 fields. MARC forces the choice of one predominant Content Type, whereas the default in RDA doesn't require this forced decision, but recognizes it as an alternative. Rhetorical question: How consistently have libraries added all relevant additional content types to 006 fields? Thomas Brenndorfer Guelph Public Library
