Electronic Location Identifier

Bibliographic identifier for a document that does not have traditional printed page numbers.


This element acts in the same way as a page identifier for a document that does not have traditional page numbers; the value could be an article identifier, DOI, etc., for example, “E70”.
External Identifier: This element holds an external identifier, assigned to an article by a publisher, an archive, or library to help cite an article that is born digital and will never have page numbers. The contents of this element should not be confused with the @id attribute, which holds an internal document identifier that can be used by software to preform a simple link.

Related Elements

A number of elements in the Suite relate to page numbers:
  • <fpage> names the page number on which a work begins;
  • <lpage> names the page number on which a work ends (which should be the same page number or a number larger than the starting page number);
  • <elocation-id> replaces the start and end page elements just described for electronic-only publications;
  • <page-range> records discontinuous page ranges; and
  • <page-count> holds the total page count, if the publisher has provided one. Typically this element records what the publisher said and makes no validity claim. The element <page-count> should be used only in metadata. The citation elements (<element-citation> or <mixed-citation>) use the element <size> to tag the total page count of a cited work. (Historical Note: The deprecated <nlm-citation> element still uses the <page-count> element.)
Best Practice: The <page-range> is intended to record supplementary information and should not be used in the place of the <fpage> and <lpage> elements, which are typically needed for citation matching. The <page-range> element is merely a text string, containing such material as “8-11, 14-19, 40”, which would mean that the work began on page 8, ran through 11, skipped to page 14, ran through 19, and concluded on page 40.
