There are various tools to help you find open access versions of articles that are otherwise only available with a subscription to the journal (or by paying an access fee). These include:
- OA DOI (https://oadoi.org/): If you know the DOI (digital object identifier) of the article you’re looking for, you can paste it onto the end of this web address to find open access versions of the article.
- Unpaywall (http://unpaywall.org/): This is a browser extension for Firefox and Google Chrome. Once you’ve installed it, any time you find an article behind a paywall, you can click on the padlock icon on the right hand side of the screen and be taken straight to an open access version of the article, if there’s one available.
- Open Access Button (https://openaccessbutton.org/): a similar tool to Unpaywall, this also allows you to search for an article directly from their website and request copies of articles from authors.
- Canary Haz (http://www.canaryhaz.com/): a new tool, currently being tested, which as well as finding open access versions of articles can also help access content the library has subscribed to whilst off campus, and link from the pre-print to the final published version of an article. Sign up required for free service, company will be making a premium version available.
