Convertibility of space and defense resources to civilian needs : a search for new employment potentials / compiled for the Subcommittee on Employment and Manpower of the Committee on Labor and Public Welare, United States Senate. (OCLC #28090162)

This resource is the second volume of a set that is continuously paged. RDA 3.4.5.7 on Pages, Etc., Numbered as Part of a Larger Sequence says to. record the first and last numbers of the pages, as in:

pages 587-1106

This volume also has pre-pages numbered with Roman numerals. If it had only those pages, the extent would be recorded:

vii pages

but I don’t see an example for combining these two forms. It seems reasonable to do:

vii pages, pages 587-1106

but the cataloger who made this copy chose the format:

vii, pages 587-1106

which is also clear.
