The author-date method employs both a reference list and in-text citations which note the author’s last name, year of publication, as well as the page number(s) from which you’re citing.
In the author-date system, a citation in the text usually appears in parentheses and includes only the first two elements in a reference list--the author and the year of publication, with no intervening punctuation. A page number or other locator may be added, following a comma. Terms such as editor or translator, abbreviated in a reference list, are omitted from a text citation. In a parenthetical reference to two or more works, a semi-colon usually separates each from the next. (15.7) In electronic formats, text citation may be linked to their corresponding reference list entries. Chicago Manual of Style, 17th ed. (15.5) page 895.
In a references list entry, the year of publication is the second element, following the author's name. The elements are separated by periods, and the first listed author's name, according to which the entry is alphabetized in the reference list, is usually inverted (last name first). Titles are capitalized headline-style, unless they are in a language other than English (8.159, 11.6); Titles of larger works such as books and journals are italicized; and titles of smaller works such as journal articles are presented in roman and enclosed in quotation marks. Noun forms such as editor, translator, volume and edition are abbreviated, and verb forms such as edited by and translated by are spelled out. (15.6)
