Article Subtitle

The subordinate name of a journal component such as an article


Subtitle. In the article metadata, the article subtitle and title are identified with two different elements and tagged separately, using the <article-title> and <subtitle> elements. Within a bibliographic reference citation, the subtitle cannot be preserved separately as this Tag Set identifies no cited-subtitle elements.

For references using either the <element-citation> or the <nlm-citation>, since these two reference models do not permit untagged text there are two choices:

For references using the <mixed-citation>, there are two choices:

Best Practice. Although this Tag Set cannot enforce either practice, retrieval performance will be enhanced if the subtitle is consistently placed within the <article-title> element (or the <source> element for book titles, proceedings titles, and other titles) for all cited material. Either with a <named-content> or as untagged text, the subtitle is easy to lose to searching. It is also not always obvious, particularly with historical or foreign material, which part of a multipart title is the main title and which the subtitle.

Related Elements

There are several elements concerned with the title of an article, all contained within the container 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-group> is also a container element, inside the <title-group>, that holds together a translated title (<trans-title>) and its translated subtitle (<trans-subtitle>). The translated title is a version of the title translated into a language other than the original language of publication, and the matching subtitle is a version of the subtitle translated into a language other than the original language.
