Pages (page range/article number)
This field indicates the first and last page of an article (e.g. "101–102") or the article number (e.g. "456754").
If possible, the article number should be entered together with the number of pages (e.g. "12345, 19 pages"). If the publication has no continuous page numbering, then the total number of pages should be used (e.g. "27 pages").
