Total number of pages in a work in print; by convention, each page or partial page is counted as one. Electronic-only works do not traditionally have page counts.
This element is used both within the metadata describing a standards document and inside the deprecated NLM citation element.
Best Practice Metadata Usage In the metadata for a standard, the <page-count> element can appear at two different levels: inside the <counts> element and one level up, directly inside one of the metadata container elements (<std-meta>,<iso-meta>, etc.) This double placement was necessary for ISO STS backwards compatibility. Best Practice going forward is to place the <page-count> element inside <counts>.
Best Practice for Counting: Although a NISO STS standards-producing organization could choose to record all the counts of objects in a standard using the <count> element, Best Practice is to use the specific count elements (<fig-count>, <equation-count>, <word-count>, etc.) whenever possible, using the <count> element only for ad hoc counts, organization-specific counts, standard-specific counts, and similar.
