Unpaywall - Frequently asked questions

When is the official release?

April 4th. The extension mostly works right now, but we're still tweaking things.

Who's behind Unpaywall?

We're Impactstory, a nonprofit working to make science more open and reusable online. We're supported by grants from the National Science Foundation and the Alfred P. Sloan Foundation

Why did you make it?

We loathe paywalls. Now more than ever, humanity needs to access our collective knowledge, not hoard it. Lots of scholars feel the same; that's why they upload their papers to free, legal servers online. We realized that the missing link is in getting these free resources to the people who want them, at the right time. By using a browser extension, we can do that, leveraging the toll-access distribution system to bring open access to the masses.
