This I think is a good fit. One could say that neither Extent of Text nor Extent of Still Image apply for a comic book or graphic novel as the resource is a hybrid of content types and so one would not be forced to use either subset of instructions. Who says we should treat a comic book as an exception for recording extent in RDA 3.4.1.3? If it's not an exception then the main instruction applies. The main element is still called "Extent" which is used when we don't use "Extent of Text" or "Extent of Still Image." Using the element name is a useful flag indicating that the exceptions for extent are not being used. Extent is first and foremost the number of carrier units. One could also apply the alternative in RDA 3.4.1.3 and just say instead of 1 volume: 1 comic book For the number of subunits there is no specific example matching a comic book in the cases listed in 3.4.1.7, but I wouldn't take the cases as exhaustive. The cases all follow the main instruction of using the number of carrier types as the main value for Extent. One could take the same freedom allowed in applying as subunits the extent of a parallel counterpart (printed text in a volume): 1 comic book (ix, 45 pages) Colour Content is applicable. 1 comic book (ix, 45 pages) : color ; 24 cm Because 'still image' is used for a predominant content type, and there isn't a comparable instruction to use "chiefly illustrations" I would drop "illustrations" altogether. Illustrative Content has a meaning restricted to illustrations of the primary content, which doesn't make sense for a comic book, where the primary content consists of illustrations. Also the exception for using Extent of Text is to use it for printed text "with or without accompanying illustrations". I would take that mean that adding "illustrations" in 300$b means we're adding it because it accompanies the text, and if that's the case then the Extent should probably also be Extent of Text, which would mean we couldn't use "1 comic book."
