Zotero vs Mendeley vs EndNote vs RefWorks vs JabRef: Compared

What does a reference manager do?

A reference manager (also called citation manager or reference management software) is a database for your sources. Instead of typing references by hand, you import them with one click from Google Scholar, library catalogues, journal websites or via DOI. While writing, a plugin inserts citations into your text and builds the reference list automatically in the citation style you choose. If your supervisor asks you to switch from APA to Harvard, you change one setting rather than every reference.

For a dissertation with 60 to 150 sources, this saves days of work and prevents the most common formatting mistakes, such as references missing from the list or listed but never cited. The APA Publication Manual (2020) does not require any particular tool, but it does require a complete, consistent reference list, which is exactly what these tools support.

Overview as of late 2026. Features, platforms and licence models change, so check the vendor’s website and your library’s guidance before you decide.

The tools in brief

Zotero is developed by a non-profit and is free and open source. The browser connector saves references and PDFs from almost any website, the built-in PDF reader stores annotations, and thousands of citation styles are available through the Citation Style Language (CSL). Group libraries let you share sources with a team. Free cloud storage for PDFs is limited; references themselves sync without limit.

Mendeley is owned by the academic publisher Elsevier. The current Mendeley Reference Manager replaced the older Mendeley Desktop; citations are inserted with the Mendeley Cite add-in for Word. It offers a PDF reader with highlights and notes and syncs your library through a free account.

EndNote (Clarivate) is a long-established commercial program, especially common in medicine, nursing and the life sciences and at universities with site licences. Cite While You Write integrates with Word; libraries can be shared with colleagues.

RefWorks (ProQuest/Clarivate) is entirely web-based and available only through an institutional subscription. If your university subscribes, you log in with your university account.

JabRef is a free, open-source editor for BibTeX/BibLaTeX files. If you write in LaTeX or Overleaf, it manages your .bib file directly. In German-speaking countries Citavi is also widespread, mostly on Windows and via campus licences.

Decision guide

Answer these questions in order:

• Does your library offer training and support for one tool? Use it; support saves more time than features.
• Do you write in LaTeX or Overleaf? Zotero (with BibTeX export) or JabRef.
• Do you write in Google Docs? Zotero or RefWorks (if your university subscribes).
• Do you work on Linux? Zotero or JabRef.
• Do you want to keep your library free after graduation? Zotero, JabRef or Mendeley; check what happens to institutional licences when you leave.
• Do you collaborate on a literature review? Zotero group libraries, shared EndNote libraries or RefWorks shared folders, depending on what your co-authors use.

Typical workflow for a thesis

Whichever tool you choose, the workflow is similar:

• Collect: import references via browser extension, DOI/ISBN or database export (RIS). Attach the PDF if available.
• Check: correct metadata immediately: author names, year, title capitalisation, journal name, volume, issue, pages, DOI.
• Organise: folders or collections per chapter, tags for themes, notes or annotations with key arguments.
• Cite: insert citations with the word processor plugin; add page numbers for direct quotes.
• Build the list: let the plugin generate the reference list; do not edit it manually (changes are overwritten).
• Finalise: before submission, check the list once against your style guide and keep a backup copy with live citations.

Limits and common errors

Reference managers only output what you put in. Typical problems: titles in ALL CAPS from databases, missing DOIs, wrong item types (a book chapter saved as a book), conference papers formatted as journal articles, and duplicate entries. Run a duplicate check and look through the list before submission.

Also check your university’s preferred style: “Harvard” exists in many variants, and some departments have their own style file. Professor Digital’s free citation generator formats single references in APA, Harvard, MLA and Chicago, which is a quick way to double-check a tricky entry.

Switching tools without losing your library

You can move between almost all reference managers. Export your library as RIS or BibTeX (include notes and attachments if the option exists) and import it into the new tool. Zotero can also import directly from Mendeley and other tools. Citations already inserted in a Word document, however, usually cannot be converted between tools: they belong to the plugin that created them. So switch before you start writing, or keep one document per tool.
