Access Date for Cited Work


The date on which the work that is cited was examined.


Some online resources are changing so quickly that a citation (<citation> or <nlm-citation>) to the resource is not complete without the date on which the cited resource was examined, because a day before or a day later, the relevant material might be different.

For extensive examples of formatted <nlm-citation>s including use of <access-date>s in <nlm-citation>s, see: Sample PubMed Central Citations. To see tagged versions of these examples, see: Sample PubMed Central Citations - XML Tagged.

Related Elements

The related element <time-stamp> is used to record the time stamp that was found on a cited resource when it was examined, not the time when the resource was examined (for time-stamped resources).

Model Description

Text, numbers, or special characters.
