What is a Citation Generator?
A citation generator is a tool that automatically formats source references according to academic style guides like APA, MLA, Chicago, and Harvard. Instead of memorizing complex rules about italics, punctuation, and author name formatting, you enter the details of your source and get a perfectly formatted citation instantly. Our free citation generator supports 12 source types and four major citation styles, making it the only tool you need for any research paper, essay, or academic project.
The APA style guide, now in its 7th edition, is the most widely used citation format in social sciences, while MLA dominates humanities and Chicago is preferred in history.

Understanding Citation Styles: APA vs MLA vs Chicago vs Harvard
APA (American Psychological Association) 7th Edition uses author-date in-text citations and an alphabetical References page. Titles of standalone works are italicized, and only the first word of article titles is capitalized. APA is the standard in psychology, nursing, business, and most social sciences. It emphasizes the year of publication, reflecting the importance of recency in scientific research.
MLA (Modern Language Association) 9th Edition uses author-page in-text citations and a Works Cited page. It emphasizes the author and the page number to help readers locate specific passages. MLA is used in English literature, comparative literature, foreign languages, and some humanities disciplines. It uses a standardized container system for organizing source elements.
Chicago Manual of Style 17th Edition offers two systems: Notes-Bibliography (footnotes plus a bibliography, favored in history and arts) and Author-Date (similar to APA, used in sciences). The Notes-Bibliography system uses superscript numbers in the text that correspond to footnotes or endnotes at the bottom of the page or end of the chapter.
Harvard referencing is an author-date system widely used in the United Kingdom, Australia, and many other countries. It is similar to APA in structure but has its own conventions for punctuation, capitalization, and the use of “Available at:” for URLs. There is no single authoritative Harvard guide, so formatting can vary slightly between institutions.
Frequently Asked Questions
What is the difference between a citation and a reference?
A citation is a brief mention of a source within the text of your paper (like an in-text citation), while a reference is the full bibliographic entry that appears at the end of your paper in the Works Cited, References, or Bibliography section. Citations point readers to the corresponding reference for complete source details.
Which citation style should I use?
The citation style depends on your field of study. APA is standard for psychology, education, and social sciences. MLA is used for literature, languages, and humanities. Chicago is common in history and some humanities. Harvard is widely used in the UK and Australia. Always follow your instructor's or publisher's requirements.
How do I cite a source with no author?
In APA, use the title of the work in place of the author (in italics for standalone works, in quotes for articles). In MLA, begin with the title. In Chicago, start with the title as well. In Harvard, use the organization name or start with the title. All styles have specific rules for handling anonymous works.
How do I cite multiple authors?
Rules vary by style. APA lists up to 20 authors before using an ellipsis. MLA uses 'et al.' after the first author when there are three or more. Chicago lists up to three authors, then uses 'et al.' for four or more. Harvard lists up to three, then uses 'et al.' Our generator handles these rules automatically.
How do I create an annotated bibliography?
An annotated bibliography includes a citation followed by a brief summary and evaluation of each source (usually 100-200 words). Generate your citations using our tool, then add your annotation paragraph beneath each entry. Most annotated bibliographies use the same formatting style as your paper.
Can I switch citation styles after creating citations?
Yes. Our citation generator stores the structured data for each source, so switching between APA, MLA, Chicago, and Harvard re-formats all your citations instantly. You do not need to re-enter any information when changing styles.
