How to use the Citation Generator
Enter a DOI (Digital Object Identifier) to automatically fetch article metadata and generate a perfect citation in APA, MLA, Chicago, or Harvard format. You can also enter any website URL to cite a web page. Click Copy to copy the formatted citation directly to your clipboard — ready to paste into your essay or bibliography.
Find the DOI on the article page, in your library database, or on doi.org.
When to use each style
APA: Psychology, education, social sciences. MLA: Literature, humanities, arts. Chicago: History, some humanities. Harvard: Business, economics, sciences (UK/Australia).
What is a DOI?
A Digital Object Identifier is a permanent link to an academic article. It looks like 10.1038/nature12345. Find it on the article page or in Google Scholar.
Always double-check
Auto-generated citations can have errors — especially with unusual author names or missing metadata. Always verify against your style guide before submitting. Your professor will notice mistakes.
Should you include citations in an abstract?
As a rule, the abstract is a self-contained summary of your research, and it should not carry citations. The reader needs the key findings, method, and conclusion up front; the reference list at the end of the paper is where sources are credited. Citing a source inside the abstract forces readers to chase the reference before they can judge the summary, which defeats the purpose.
The main exception is when your study directly extends or contradicts one landmark work — in that case a single citation can orient the reader. APA, MLA, and Chicago all permit this, but keep it to one or two sources at most.
Frequently asked questions
Can I generate a citation from just a URL or DOI?
Yes. Paste a DOI (the 10.xxxx identifier on every academic article) or any web URL into the generator, and it looks up the source's metadata and builds the formatted reference automatically. For materials without metadata — rare books, lectures, personal communications — fill in the fields manually; the generator formats them in all four styles.
What is the difference between in-text citations and a reference list?
In-text citations appear where you use a source and point to it briefly — (Smith, 2021) in APA, (Smith 45) in MLA. The reference list at the end contains the full details of every cited work. The two are inseparable: every in-text citation must have a reference entry, and every reference entry must be cited in the text.
Why do different fields use different citation styles?
Styles serve different research cultures. APA emphasizes the date because psychology and the sciences care about currency of research; MLA emphasizes the page because literary scholars quote specific passages; Chicago's footnotes allow rich commentary alongside citations. Your professor's style requirement usually reflects your field's convention — not a random choice.
Does a citation generator guarantee a perfect bibliography?
It eliminates most formatting errors, but always proofread the output: check author name order, capitalization of titles, italic vs. regular text, and page numbers against the actual source. A generator can only work with the metadata it receives — a missing volume or an extra author changes the entry. Reviewing generated citations is part of responsible source use, not an optional step.
