Have you tried to access a journal article online but couldn’t get access to the full text of the article?

Did you try to access the article using OpenAthens?  

OpenAthens (https://openathens.org/about-us/) is a system that most UK Universities use to provide their students and staff with access to digital resources off-campus. OpenAthens is the piece of software that makes a digital library really powerful, because it enables you to access online journal articles, e-books and databases whenever you want and from wherever you are.
