Formatting follows APA 7th edition, MLA 9th edition and Chicago 18th edition (author-date). The active version is shown next to the preview.
One author, two authors, three or more authors, an organisation as author and no author at all each produce their own form.
A source without an author starts with its title; a source without a year uses n.d. Empty placeholders are never left in the output.
Citation punctuation is fiddly and every style differs on author order, italics, parentheses and what to do when a field is missing. Copying a half-remembered template usually produces a reference that is almost right.
Four source types are supported: books, journal articles, web pages and videos. Add several sources to build a bibliography that is sorted automatically by the first author’s surname.
Book · John Smith · 2020 · Understanding Rivers · Example Press => APA: Smith, J. (2020). Understanding Rivers. Example Press. / In text: (Smith, 2020) MLA: Smith, John. Understanding Rivers.

Prefix the author line with “org: ”, for example “org: World Health Organization”.
