Each citation style has its own specific rules for ordering author names, formatting a publication date, and punctuating a title, and those rules genuinely differ between APA, MLA, and Chicago rather than being cosmetic variations on the same format, which is exactly why a citation formatted correctly in one style is often wrong in another even though it lists the same underlying source. This tool builds a properly formatted citation in whichever style is required, for a book, a website, a journal article, or another source type, applying that style's specific formatting rules rather than a generic one-size-fits-all citation format. Useful for formatting a bibliography correctly in whatever style an assignment or publication requires, converting a citation from one style to another when a paper's requirements change, or double-checking a citation actually follows its style's specific rules before submitting a paper.
