Deep veils : Erik L’Heureux and Pencil Office / Erik L’Heureux and Grit Vltavsky. (OCLC #880198268)
This volume is oddly sized and bound. The white part is the cover, wrapped around the larger beige signatures; you can see page number “1” poking over the top. There are also about 15 (double-sided) sheets of different sizes tipped in throughout the book that are unnumbered (no space left in the page sequence), so I guess they are plates? Many of the numbered pages have only illustrations, and some smaller pages have only text; not how I usually think of plates, but I think they qualify.
RDA 188.8.131.52.14 on the dimension of volumes mentions the situation where the volume contains separate text blocks of varying dimensions (which is not precisely this case); it says in that case to record the height (or height × width) of the binding only – I think the spirit of this instruction is to record the dimension of the carrier, which is what is recorded in the copy I found:
I mentioned the odd plate sizing in a note for identification purposes:
500 __ ǂa Plates of different sizes, smaller than numbered pages.
so I also included the plates, as they are mentioned in a note, per RDA 184.108.40.206.
