Related Elements

Within the article metadata, the <series-title> element names a collection of articles within an issue or a collection of similar articles across multiple issues, while the <series-text> element provides textual description (if any) of the series.

The similarly named but unrelated element <series> element is used in elements that include bibliographic citation information (such as <element-citation>, <mixed-citation>, <related-article>, <related-object>, and <product>) to identify publications that are part of a published series. In this context, the <series> element acts as a container element to hold any series data mentioned in the reference.
