Both Zotero and Covidence can store, manage, and deduplicate citations. However, they differ significantly in their application and scope.
What is Zotero?
Zotero is a free citation management software that includes a desktop application and a browser extension.
What you can do with Zotero:
- Save bibliographic information from any page on the internet.
- Import citations through various file types (e.g. BibTeX, RIS, Zotero RDF).
- Sort your citations into folders and sub-folders.
- Create a single citation or an entire reference bibliography in any citation style.
Learn more about accessing and using Zotero:
- Visit our Citation Management subject guide for more information about accessing and using Zotero.
- Visit the Zotero website for tutorials and information on how to make the most out of Zotero.
- Visit the Zotero blog and forums to troubleshoot very specific issues that you may encounter.
TIP: You can use Google to search within the Zotero blog and forum by adding site: forums.zotero.org/discussions or site: zotero.org/blog/ after your Google search query. This limits your search to only those sites. For example, to learn how to add full-text PDFs to your saved citations, search full text pdf site:zotero.org/blog/.
What is Covidence?
Covidence is a web-based software that lets members of a research team collaborate through the various stages of a knowledge synthesis project (such as a systematic review). Nova Scotia Health has an institutional license to Covidence, which means Covidence is now free to use for Nova Scotia Health staff!
What you can do with Covidence:
- Upload citations
- Screen titles and abstracts
- Screen full-text articles and resources
- Complete data extraction
Learn more about accessing and using Covidence:

What’s the difference?
Zotero is great for organizing literature sources, creating reference lists, and assisting with in-text citation. You will likely find Zotero more useful for everyday research needs.
Covidence is best for conducting knowledge synthesis projects with a team that will lead to a published review article. Outside of scholarly publications, Covidence could also be used by a team to screen through a large amount of potentially relevant literature to find those that are most relevant to your specific needs.
Both tools have distinct features that make them suitable for different purposes. The table below lists the different strengths of each tool, depending on your project needs:
