What you need
For a website, Chicago (author-date) expects these fields at minimum:
- Author or organization
- Year of publication
- Page title
- Website / organization name
- URL
- Access date (some styles)
Common mistakes
- Citing a dynamic page without an access date — crucial because the content can change.
- Using the URL as the title. The title is the page heading; the URL is a separate field.
- Mixing bibliography formatting with in-text citation rules. Reference-list entries and in-text cites follow different patterns — use the style's official guide for both.
- Forgetting the DOI. When a DOI exists, most styles now require it (usually as a full https://doi.org/… URL).
