The full title of a journal article or other journal component such as a book review
The <article-title> element is used in two contexts: as a part of the metadata concerning the article itself and as part of bibliographic reference metadata inside bibliographic citations (<citation> and <nlm-citation>).
In the article metadata, the article subtitle and title are two different elements and should be tagged separately, using the <article-title> and <subtitle> elements. Within a bibliographic reference citation, the subtitle cannot be preserved separately. For citations using <citation>, it is possible to place the subtitle with the title in the <article-title> element (or the <source> element for book titles, proceedings titles, and other titles) or to leave it as untagged data characters within the text of the reference. For references using <nlm-citation>, the subtitle must be included with the title, since that reference model does not permit untagged text. Although this Tag Set cannot enforce either practice when using <citation>, retrieval performance will be enhanced if the subtitle is consistently placed in the <article-title> element (or the <source> element for book titles, proceedings titles, and other titles) for all cited material, so this is considered best practice.
For extensive examples of formatted <nlm-citation>s including use of <article-title>s in <nlm-citation>s, see: Sample PubMed Central Citations. To see tagged versions of these examples, see: Sample PubMed Central Citations - XML Tagged.
