Questions
Which Chicago is this?
The author-date system of the Chicago Manual of Style, 18th edition, used across the sciences and social sciences. The notes and bibliography system is not offered yet.
Where does the citation data come from?
From Crossref, the registry publishers use for DOIs, and from OpenAlex for books and papers Crossref does not list. We format what the record says and never fill a gap with a guess.
Why does a name or place in my title look lowercase?
Styles that use sentence case lowercase every word after the first. We keep acronyms, but we cannot tell a proper noun from an ordinary word, so check names of people, places and organisations before you submit.
Is it free?
Yes. The generator, the DOI converter and the reference checker need no account. A free account adds a library you can export from.
