Need a particular article, but can't find the full text? The Open Access Button is a resource for finding free, legal research articles delivered instantly or automatically requested from authors.
Try the Open Access Button search to see if an OA version exists.
Thanks to the efforts of librarians, scholars, and technologists and the Open Access movement it’s easier than ever to legally and freely read millions of articles. Our sources include all of the aggregated repositories in the world, hybrid articles, open access journals, and those on authors personal pages.
The Open Access Button does not use content from ResearchGate or Academia.edu.
When an article isn’t freely available we ask the authors to share it by putting it into a repository. We help authors share quickly, legally, and widely so that not only you get access - but everyone does, forever!
