In-text citation
Also called: citation in text, text citation
A short pointer placed in the body of your paper that identifies which source a statement came from and sends the reader to the full reference.
An in-text citation is the small marker inside a sentence or at the end of it — (Larsen, 2024), (Larsen 12), or [4] — that tells the reader which entry in your reference list supports what you just wrote. It is deliberately short. Its only job is to be unambiguous enough that exactly one reference entry matches it.
Every citation style pairs one in-text form with one list form, and the two have to agree. If your in-text citation says (Larsen, 2024), the reference list must have an entry beginning with Larsen and dated 2024. Mismatches between the two are the single most common reason a bibliography loses marks, and they are what a citation checker looks for first.
Author–date styles put the author and year in the text. Numeric styles replace that with a number keyed to the order of first appearance. Note-based styles move the whole citation into a footnote and leave only a superscript number in the sentence.
