The Chicago Manual of Style is currently in its 18th edition.
NOTE: For lectures, papers presented at meetings, and speeches that are published in other sources, the Chicago Manual of Style indicates that the material should be cited in the medium it was published. For example, if the lecture was published in a book, cite it as a chapter in a book. For live lectures, paper presentations, and speeches, see the formats below.

Add information about sponsorship, location (if applicable), and date of the meeting following the title. If that information is available online, you can include a URL. These citations are normally limited to the text or a note, and are not included in a bibliography. Previous editions of the Chicago Manual of Style required parentheses around this added information, but parentheses are no longer used for this citation.
