Insert the reference into the reference list alphabetically according to the title.
Begin the entry with the title of the reference. Italicize the title if it is a book. If it is a periodical, enclose the title in quotation marks. End with a period after the title.
Follow the title with "n.d.," the abbreviation for "no date," in parentheses.
Complete the rest of the reference entry as you would for any other entry. For example, if your entry is for a periodical, complete the entry as you would for any other periodical that did include an author and date. For example:
"Child Brides of Afghanistan." (n.d.), Childhood Issues, 54-57.
