Books
For books, use the year of publication in the citation. The date (year) follows the publisher name preceded by a comma. If the year does not appear on the title page, look on the verso page (the back of the title page). Usually, the latest copyright date is cited.
Example:
New York: Scribner's, 2001.
Chicago: U of Chicago, 1999.
For republished books, give the original publication date, followed by a period, before the publication information. Include the most recent publication date after the publisher name.
Example:
Holier, Denis, ed. A New History of French Literature. 1989. Cambridge: Harvard UP, 1994. Print.
Journals
In general, the date used in a scholarly journal citation will be the year of publication (in parenthesis). Do not include the month or season.
Example:
Gregory, Marshall. "Curriculum, Pedagogy, and Teacherly Ethos." Pedagogy 1.1 (2001): 69. . . . . .
Magazines
For magazines published every month or every two months, give the month(s) and year. Abbreviate the months (except May, June, and July). [Do not give volume and issue numbers].
Environment Apr. 2000: 17-21.
Tikkun Nov.-Dec. 2007:27+.

No date
When no publication date can be found, use n.d. (for no date) in the citation.
Example:
New York: U of Gotham P, n.d.
When you approximate the date, but are uncertain about the accuracy of the information, add brackets around the date and a question mark.
Example:
New York: U of Gotham P, [2003?].
