Thank you for bringing this up again. Here is a link to an earlier posting by me on this issue, which only generated one response:
https://listserv.collectionscanada.gc.ca/cgi-bin/wa?A2=RDA-L;db70d096.1307 There is some more discussion of the issue in a longer thread that started out as a query about the new RDA glossary definitions of "leaf" and "page," which limits them to units of "extent of text." https://listserv.collectionscanada.gc.ca/cgi-bin/wa?A2=RDA-L;9a78b4cd.1307 As I asked in the first post in that thread: "If you have a volume containing only images, such as reproductions of photographs or drawings, what do you call the things they are printed on? And how do you reckon the extent of the resources containing them?" -------------------------------------------------------- Kathie Coblentz, Rare Materials Cataloger Collections Strategy/Special Formats Processing The New York Public Library, Stephen A.
