Overview
Unpaywall is a browser extension and open database that provides free access to research papers that are usually behind paywalls. It works by automatically searching for open access versions of articles as you browse scholarly journals and databases. When Unpaywall finds a free version, it displays a prominent link, allowing users to access the paper without paying a subscription fee. The underlying technology relies on a comprehensive index of open access content harvested from legal sources worldwide. Unpaywall primarily targets researchers, students, librarians, and anyone who needs access to scientific literature but lacks institutional subscriptions. It helps overcome barriers to knowledge access and promotes wider dissemination of research findings.
