Browser plug-in

Several browser plug-ins can help you tell if an article you would like is Open Access. Installing a free plug-in in your browser will give you access to the articles. Beware of the whish plug-ins work in whish browsers.

Contact the author - use your network

Alternatively you can try contacting the author/s directly, as the author often has the right to share his/her articles with peers. Use your personal network or use established research networks supporting sharing of articles between peers i.e. ResearchGate or Academia.edu.
