Alternative routes to scholarly articles and research outputs

Plugins, browser extentions and interlibrary loans

You can download and use browser extensions or plug-ins, or search directly in your favourite repository in order to find open access articles. Below we list examples of plug-ins, open archives and search services. Many libraries also integrate these services in their link resolvers for seamless access via their discovery services.

Researchers may share articles between themselves if this is permitted by agreements with their publishers, the so-called ‘scholarly sharing.’ Please refer to Sherpa/Romeo to check current terms for the journal in question. When using the plug-in Open Access Button and hitting paywalled articles, requests to authors are sent asking them to deposit their articles in an open institutional or subject repository. There are also a number of social platforms for researchers, e.g. ResearchGate and Academia.edu.

There are a number of browser extensions or plug-ins for Chrome, Firefox, and Safari which can be installed to facilitate finding articles which are open access:

Unpaywall

They also offer integrated services for libraries external link , as interlibrary loans (ILL/DDS). When OA Button hits a paywall, the service also sends off requests to authors asking them to deposit their articles in a subject or institutional repository in order to make their research open. Open Access Button is a non-profit organisation.

Google Scholar Button
