Citation Generator — APA, MLA & Chicago Formats

How the Generator Assembles a Reference

A reference is not free text. Each style guide fixes the order of the elements and the punctuation mark between every pair of them, and nearly all of the difficulty in citing by hand is remembering which mark goes where. This tool stores one assembly rule for every combination of style and source type, slots in the fields you filled, and drops the ones you left blank instead of leaving an empty bracket or a stranded comma behind. For a book in APA 7th the rule is:

MLA 9th keeps the same four elements but moves the year to the end, italicises the title and separates publisher from year with a comma rather than a full stop:

That single difference is why copying a reference from one paper into another with a different style rarely works. Nothing is missing — the pieces are simply in the wrong order with the wrong separators, which is exactly what a marker checking a reference list is looking at.

The pattern for each style and source

Every combination the tool supports is listed below. Fields you leave empty disappear from the pattern, so a journal article without an issue number closes the volume and moves straight to the pages.

The in-text column shows what the green strip under the output produces. APA carries author and year, MLA carries the author alone, and Chicago's author-date system pairs the two without a comma. Where the year is missing, APA and Chicago substitute n.d. — the standard abbreviation for "no date".

What the BibTeX export contains

Export BibTeX writes every citation generated during the current visit — not just the one on screen — into a plain text file called citations.bib. Journal sources become @article entries, websites become @misc, and everything else becomes @book. The citation key is built from the author's surname, the year and the entry's position in the list, lowercased with punctuation stripped, so a 2024 Smith reference becomes something like smith20240. The exported fields are author, title, year, publisher, journal, volume and URL; issue number and page range are not carried across, so add those in your reference manager if your bibliography style needs them.

Check the Output Before You Submit

The generator is a formatter, not a proofreader. It takes what you type and arranges it — it does not look anything up, does not verify that a DOI exists, and does not know whether the name you entered is a person, an organisation or a typo. Three things are worth a second look on every reference.

• Author names are printed verbatim. Type Smith, J. and you get Smith, J.; type John Smith and you get John Smith, which no style wants in a reference list. Because the in-text helper reads the text before the first comma, entering the name the wrong way round also produces (John) instead of (Smith).
• Italics are marked with tags, not applied. Elements the tool italicises come out wrapped in <em> markers rather than as real italics. It also does not mark every element a style guide wants italicised — an APA book title, for instance, comes out plain. Apply the italics yourself in your word processor.
• Spacing around punctuation is approximate. Fields are joined with single spaces, so a journal reference can arrive with a space before a comma or a full stop. Tidy those by hand — a marker will notice them before they notice a missing issue number.

Several elements that real reference lists need have no field here at all: DOIs, editors and translators, edition numbers, chapters in edited collections, place of publication for older Chicago references, and the second and later authors of a multi-author source beyond whatever you type into the single author box. If your source needs one of those, generate the closest match, then add the missing element by hand against the published style manual.

Which Style Does Your Field Use

If your brief does not name a style, the discipline usually implies one. APA, published by the American Psychological Association and now in its seventh edition, dominates psychology, education, nursing and the social sciences; its author-date format makes the recency of a source visible in the body text, which matters in fields where a 1998 finding may have been superseded. MLA, from the Modern Language Association and now in its ninth edition, is standard in literature, languages and cultural studies; its in-text citation gives author and page rather than author and year, because a scholar of a novel needs to point at a passage, not a publication date.

Chicago, defined by The Chicago Manual of Style and currently in its seventeenth edition, runs two systems in parallel. Notes-bibliography uses numbered footnotes with a bibliography at the end and is common in history and the arts. Author-date looks much like APA and is used in the sciences and social sciences. The in-text helper on this page produces the author-date parenthetical; if your department expects footnotes, use the generated reference as the bibliography entry and write the notes separately.

Whichever you use, the rule that actually matters is consistency. A reference list where every entry follows the same pattern reads as careful work even if one element sits a millimetre from where the manual puts it. A list that mixes APA and MLA conventions looks assembled from whatever each source's website offered, which is usually exactly what happened. Generating every entry in one place is the simplest way to avoid that.
