Publication Date


Date this article was published or released in one particular format, for example, as an preprint electronic document


As part of the article metadata, the <pub-date> is allowed to repeat; each repetition can take a pub-type attribute to distinguish which form of publication, for example, print publication, preprint distribution, electronic publication, etc.

While most publication dates will either be a season and a year (e.g., Spring 1999) or a year with a possible day and month (e.g., January 1, 1999), sometimes the publication date will identify both the season and date. A publication date of “Spring 1999; January 29, 1999” should be tagged:

<pub-date pub-type="pub">
