What is the difference between Notes-Bibliography and Author-Date?

Notes-Bibliography (NB) uses numbered footnotes or endnotes paired with a bibliography, and is common in literature, history, and the arts. Author-Date (AD) uses parenthetical in-text citations like (Smith 2023) paired with a reference list, and is common in the sciences and social sciences.

Which edition of the Chicago Manual of Style does this follow?

This tool follows The Chicago Manual of Style, 17th edition (2017), the current standard for Chicago formatting.

How do I format multiple authors?

Enter each author as "First Last" separated by semicolons (e.g., "Jane Smith; John Lee"). For Notes-Bibliography, the first author is inverted (Last, First) in the bibliography entry only. For more than three authors, the tool uses "et al." in notes and in-text citations.

What if there is no publication date?

Leave the year field blank and the tool inserts "n.d." (no date) in the appropriate position.

Do I need a DOI for journal articles?

A DOI or stable URL is preferred for online journal articles. If neither is available, you may omit it for print sources.

What is a short note in Notes-Bibliography style?

After the full footnote appears the first time, subsequent citations use a shortened form: Last Name, "Short Title," page. This tool displays the full note form; use the short note for repeat citations.
