Although that sounds like a really good idea, without an added option, unfortunately, I do not think the RDA instructions for Extent of Text (3.4.5.2) do not allow us to use 'other' terms.
Even though 3.4.1.3 says " (For instructions on using other terms to designate the type of unit see 3.4.1.5.)" and 3.4.1.5 allows alternative terms, continuing down 3.4.1.3 takes us to Exceptions for Cartographic resources, Notated music, Still images, Text, and Three-dimensional forms. For all of those types of resources, except Notated music and Text, the recording instructions say "If none of the terms listed above is appropriate, use a term designating the type of unit as concisely as possible". Notated music (3.4.3.1) says: "Apply the instructions given under 3.4.3.2 when recording the extent of a printed or manuscript resource consisting of notated music (with or without accompanying text and/or illustrations)" and "For resources consisting of notated music in other media (e.g., microforms), apply the basic instructions given under 3.4.1" which limits us to using only the terms provided under 3.4.3.2 for printed or manuscript notated music, although we are free to use alternative terms for 'other media'. Text (3.4.5.1) says: " Apply the instructions given under 3.4.5.2-3.4.5.22 when recording the extent of a resource consisting of one or more volumes, sheets, portfolios, or cases containing printed or manuscript text, with or without accompanying illustrations" and "For resources consisting of text in other media (e.g., microforms), apply the basic instructions given under 3.4.1", which limits us to using only the terms provided under 3.4.5.2-3.4.5.22 for printed or manuscript text, although we are free to use alternative terms for 'other media'. So, until (if) we get an added option, if it seems important for identification or selection we can, perhaps, add Details of Base Materials notes (500) for things like: Board books: e.g., "On board pages" Rag books: e.g., "On cloth pages" Bath books: e.g., "On plastic pages" And (perhaps) Notes on Dimensions (500) for things that are shaped strangely (Die-cut books) Along with the Note on Expression (500) for things that contain different content types, e.g., "A pop-up book with pull out tabs" I don't think we have a Content Type for a 'Scented book', so would that be covered under Base Material or, perhaps, Applied Material: Scent?
