Easily search for Open Access research papers with the Unpaywall add-on tool

As a researcher we have all run into a paywall at some point while searching for literature. With the new add-on tool Unpaywall, you can easily search for a legal Open Access version of the paper.

When running into a paywall, the only options were usually to personally request the author to share a pdf with you, to e-mail colleagues at other universities to check if they might have access, or to just pay up. But there is a new, safe and legal Open Access option; Unpaywall.

Unpaywall is an add-on tool  for your webbrowser, Chrome or Firefox, that will automatically search a variety of databases for legally available Open Access pdfs, based on the DOI (Digital Object Identifier) – a unique number assigned to a journal article– of the paper you are looking for. These databases could e.g. be university repositories like our own VU and VUmc repositories, researcher’s personal webpages or publisher’s archives. A color-coded link appears in the webpage scrollbar that indicates whether a pdf is available (green) or not (grey).  Download the add-on.

Unpaywall is a non-profit initiative by Impactstory that leverages green Open Access literature, i.e. self-archived by researchers. It also straight-away accentuates the importance of self-archiving, e.g. in the VU or VUmc repository, as this directly contributes to Open Access.
