Chicago A-D to Harvard converter

Paste Chicago A-D references, get Harvard. Free, no sign-up.

Paste references written in Chicago A-D and get them back in Harvard, ready to copy into Word or Google Docs. The main changes: your “References” list becomes “Reference list”, titles switch to sentence case and author names are written as in Harvard (surname and initials, joined with “and”). CiteSwap looks each reference up in the open Crossref catalogue, so authors, years and page numbers come from the publisher’s record rather than being rewritten by hand.

Do titles need different capitalisation in Harvard?

Yes. Harvard uses sentence case, capitalising only the first word, the first word after a colon and proper nouns. CiteSwap keeps titles as the publisher’s record has them, so check that capitals on ordinary words are lowered, because catalogues often store titles in title case.

How are author names written in Harvard?

Harvard: Surname and initials, joined with “and”, e.g. Suri, T. and Jack, W. Chicago A-D: First author inverted with full names, the rest in normal order, e.g. Suri, Tavneet, and William Jack. When a reference is matched in Crossref, CiteSwap uses full first names from the publisher’s record, so it can produce either form.

Is the Chicago A-D to Harvard converter accurate?

Each reference is matched against the Crossref catalogue (over 150 million records) and only accepted automatically when the title, year and first author agree. Anything uncertain is marked “Needs review” so you can pick the right match, and references that aren’t in the catalogue, like websites or local journals, are parsed from your text and marked so you can check them.
