Harvard, APA, and MLA differ in presentation — author-date versus author-page in-text format, and small punctuation and field-order differences in the reference list — but they share one non-negotiable rule: every reference must resolve to a real, existing source that says what you claim. This guide covers what changes between the styles, what doesn't, and why you should always confirm your department's exact required version. Kirla's citation generator builds references from real, resolvable records — all your writing tools in one plan.
