Remarks

The word “series” is used in this Tag Set with two very different meanings. The element <series> is used for only one of those meanings, and the two elements <series-text> and <series-title> are used only for the other.

• <series> is used in elements that include citation information (<element-citation>, <mixed-citation>, <related-article>, <related-object>, <product>) to identify publications that are part of a published series. For example, a publisher may issue a “Nursing References Series” that includes a book on the history of nursing, one on current nursing practices, one on nursing education, and another containing nurses’ professional experiences. The <series> element is used to capture that “Nursing Reference Series” information.
• <series-text> and <series-title> are used to identify a collection of articles within an issue or a collection of similar articles across multiple issues. For example, a single issue of a journal may contain numerous colloquium papers that can be identified as part of a series by including <series-title>Colloquium</series-title> in each article’s metadata. An example of a series that spans issues is the “Inaugural Article” series in PNAS. These articles from newly-elected members of the National Academy of Sciences are all part of the same series, but appear in different issues of the journal.
