<year>

Year

Year of publication of the article or other work

Remarks

For a detailed discussion on the use of <year>, see Dates in Citations.

The <year> element is used in two contexts: as a part of the metadata concerning the article itself, and as part of a description of a cited work inside a bibliographic reference (<element-citation> or <mixed-citation>).

Conversion Note: When possible, the year should be expressed as a 4-digit number, for example, “1776”, “1924”, or “0042”.

Related Elements

Within citations (<element-citation> and <mixed-citation>), this element is used to name the date of publication. The elements <year>, <date>, <day>, <month>, and <season> may all be used to describe the date a cited resource was published. Other dates inside a citation, such as a copyright date, the date on which the author accessed the resource, or a withdrawal date, should be tagged using <date-in-citation> with the @content-type attribute used to name the type of date (copyright, access-date, time-stamp, etc.).
