Entering information in this field depends on the completion of the Publication Date field. The normalized publication date should follow the ISO 8601:1988 standard, with the year in the first four digits and, if included in the publication date, the month in the next two digits and the day in the last two digits. When there is no month or day of publication, fill in the corresponding spaces with zeros. According to most publishing standards used by editors, scientific journals generally do not indicate a day of publication, only the month and year. If the date refers to a period, record the last date of the period.

Examples:

Publication Date: 2008, so Normalized Date: 20080000

Publication Date: Sept. 2009, so Normalized Date: 20090900

Publication Date: Jan.-Mar. 2010, so Normalized Date:
