The Problem to be solved

When searching for scientific literature, you often encounter paywalls, even though the document might be available for free as Open Access or through your institutional subscription. Open Access Helper is designed to assist you in both scenarios:

Open Access Availability: When the extension detects a DOI, it checks the APIs of unpaywall.org and core.ac.uk to see if an Open Access copy is available, clearly indicating this for easy and quick access.
Institutional Access: If no Open Access copy is found and you have enabled your institution, Open Access Helper can guide you to access the document through your institutional subscription at EBSCOhost, your Link Resolver, or EZProxy login.

Institutional Settings

To make the most of your institution’s subscription, you typically need to start at the library website, but not every search begins there.

With Open Access Helper, you can start your search anywhere. The extension helps you find the right access point for an article through your institution’s link resolver. If available, it can also assist you in accessing sites via EZProxy, a popular remote access solution.
