As an organization dedicated to developing free and open-source research tools, we care deeply about open access to scholarship. With the latest version of Zotero, we’re excited to make it easier than ever to find PDFs for the items in your Zotero library.
While Zotero has always been able to download PDFs automatically as you save items from the web, these PDFs are often behind publisher paywalls, putting them out of reach of many people.
Enter Unpaywall, a database of legal, full-text articles hosted by publishers and repositories around the world. Starting in Zotero 5.0.56, if you save an item from a webpage where Zotero can’t find or access a PDF, Zotero will automatically search for an open-access PDF using data from Unpaywall.
