If the author's name is used in the text, only the date of publication need be cited parenthetically (with or without the page number).<ref>{{cite book |title=The Chicago Manual of Style |chapter=15: Author-Date References |publisher=University of Chicago Press |at=Section 5: The author-date system—overview |isbn=9780226287058 |edition=17th |lccn=2017020712 |date=2017 |oclc=1055308068 }}</ref>

In-text citations are usually placed just inside a mark of punctuation. An exception to this rule is for [[block quotation]]s, where the citation is placed outside the punctuation.<ref>{{cite book |title=The Chicago Manual of Style |chapter=15: Author-Date References |publisher=University of Chicago Press |at=Section 25: Text citations in relation to surrounding text and punctuation |isbn=9780226287058 |edition=17th |lccn=2017020712 |date=2017 |oclc=1055308068}}</ref>

The full citation for the source is then included in a references section at the end of the material.<ref>{{cite book|title=The Chicago Manual of Style: Chapter 15: Author-Date Reference|publisher=University of Chicago Press |at=Section 6: Basic structure of a reference list entry |isbn=9780226287058 |edition=17th |lccn=2017020712 |date=2017 |oclc=1055308068}}</ref> As publication dates are prominent in this style, the reference entry places the publication date ''following'' the author(s) name.<ref>{{cite book |title=The Chicago Manual of Style |chapter=15: Author-Date References |publisher=University of Chicago Press |at=Section 14: Placement of dates in reference list entries |isbn=9780226287058 |edition=17th |lccn=2017020712 |date=2017 |oclc=1055308068}}</ref>
