Here's our guide to some recommended open access resources - all of these resources make many millions of research/journal articles freely available for anyone to access.
The Directory of Open Access Journals brings together several thousand fully open access journals including for business, technology and education. You can also find DOAJ journals via MetSearch.
Core provides access to nearly 80 million articles from University repositories - including Cardiff Met's very own DSpace. This is an excellent resource as it will contain open access versions of articles from many high quality journals.
Install unpaywall - this is a browser extension available for Chrome or Firefox. This allows you to leap over paywalls by giving you direct access to OA versions of published peer-reviewed research.
