简介
Open Access Helper: Effortless Access to Scholarly Articles
Stop Hitting Paywalls
You find the perfect paper. Then you see a paywall. Open Access Helper solves this problem. It automatically finds a free, legal version of the article instead. It uses data from Unpaywall and other trusted sources to find open access copies of scientific papers.
How It Works
When you open a research article, Open Access Helper checks it automatically. It looks for the article's DOI (a unique code for the paper) and searches for a free version.
If a free version exists, a badge appears. Just click the badge to open the article.
Before you click, you can hover over the badge to see what type of version it is:
- Published Version – the final, official version
- Accepted Version – the version accepted after peer review, before final formatting
- Submitted Version – the first version submitted by the authors
Easy Access Through Your University
Does your university use EZProxy or OpenAthens? Set your university's domain one time (for example: harvard.edu). After that, one click connects you to your university library, even when you're off campus.
Safe and Private
All links go to official, legal copies of the articles. We do not collect personal data. We only collect anonymous usage statistics, to help us improve the extension.
