Quick Citation Tool

There are many free quick citation tools, but we recommend ZoteroBib. It does not require an account, is open-source, and ad-free.

Paste a URL, title, or a persistent identifier like a DOI or ISBN into ZoteroBib to create in-text and reference citations. There is also an option to manually enter the source information if ZoteroBib doesn't automatically find a match.

If needed, add other styles to ZoteroBib by choosing the dropdown menu in the Bibliography section of the page. The last menu item is an option to view more styles. Choose it to look up and add the ones you want.

Reference Managers

The library's subscription to RefWorks is ending on April 30, 2025.

We recommend moving to Zotero as a free alternative for managing your references and automatically creating bibliographies in your preferred citation styles (APA, Chicago, MLA, and many more).
