<subtitle>

Document Subtitle

Subordinate part of a title for a document or document component.

Remarks

In Metadata: In the book metadata (<book-meta>) the book title and subtitle are identified separately and tagged with two different elements, the <book-title> element and <subtitle> element. In the metadata for a book component (<book-part-meta>), the title of the book component and the subtitle are also identified separately and tagged with two different elements, the <title> element and the <subtitle> element.
In Citations: Within a bibliographic reference citation, the subtitle of a document cannot be preserved separately as this Tag Set identifies no cited-subtitle elements. How the subtitle should be tagged depends on how the citation is tagged.
For references tagged with the <element-citation> element, which does not permit untagged text, there are two choices:
  • The subtitle may be included with the title inside the <article-title> element for journal articles or inside the <source> element for book titles, proceedings titles, and other titles, or
  • The subtitle may be tagged as <named-content> with a @content-type of “subtitle”.
For references tagged with the <mixed-citation> element, there are three choices:
  • The subtitle may be included with the title inside the <article-title> element for journal articles or inside the <source> element for book titles, proceedings titles, and other titles,
  • The subtitle may be left as untagged data characters within the text of the reference, or
  • The subtitle may be tagged as <named-content> with a @content-type of “subtitle”.
Best Practice In Citations: Although this Tag Set cannot enforce either practice, retrieval performance will be enhanced if the subtitle for all cited material is consistently placed within the <article-title> element for journal articles and within the <source> element for books, proceedings, reports, and other documents. When marked as either a <named-content> or left as untagged text, the subtitle is easy to lose to searching. It is also not always easy to identify, particularly with historical or foreign material, which part of a multi-part title is the main title and which the subtitle.

Related Elements

There are several elements concerned with the title of a book or the title of a book component. Such titles are contained within either the container element <book-title-group> (inside the <book-meta>) or the container element <title-group> (inside book parts, Tables of Contents, Indexes, etc.):
  • The <book-title> is the full title of the entire book in the original language of the document.
  • Book parts such as a Dedication, a chapter, an appendix, an Index , or a Table of Contents use the element <title> for their full titles in the original language of the document.
  • The <subtitle> is a subordinate or auxiliary title that adds information to one of the full titles or modifies a full title. Subtitles may modify either <book-title>s or structural <title>s.
  • The <alt-title> is another version of a book title or a structural 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, a title without equations, or a version of the title to be used in the right-running-head.
  • The <trans-title-group> is also a container element (inside either a <book-title-group> or a <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.
