The Publication Date element tells your reader when the version of the work you are citing was published. The Publication Date element may include one or more of the following components:
- a year
- a day and month
- a season
- a time stamp
- a range of dates or years
Works may be associated with more than one publication date. You should record the publication date provided by the version of the source you consult.
