Article Subtitle


The subordinate name of a journal component such as an article


Conversion Note: This may be a rarely used metadata element within the journal metadata, as many journal Tag Sets choose not to recognize subtitles, placing both the title and the subtitle information into the article title element (<article-title>).

Conversion Note: Within a bibliographic reference element (<citation> or <nlm-citation>), the subtitle is never tagged and must be subsumed within another title element. A subtitle in a citation should become part of the Article Title <article-title> element or the Source <source> element, which is used for book titles, proceedings title, and other titles.

Related Elements

There are several elements concerned with the title of an article, all contained within the wrapper element <title-group> in the article metadata. The <article-title> is the full title of the article in the original language of the document. The <subtitle> is a subordinate or auxiliary title that adds information to the full title or modifies the full title. The <alt-title> is another version of an article title, usually created so that the title can be processed in a special way, for example, a short version of the title for use in a Table of Contents, an ASCII title, or a version of the title to be used in the right-running-head. The <trans-title> is a version of the title translated into a language other than the original language of publication, and the <trans-subtitle> is a version of the subtitle translated into a language other than the original language.
