I've started using Unpaywall, a browser extension that finds open access versions of closed access publications. For example, is a search takes me to a closed Elsevier article, Unpaywall might find the Arxiv version. Too Cool. "We’re setting up a lemonade stand right next to the publishers’ lemonade stand," says Mr. Priem. "They’re charging $30 for a glass of lemonade, and we’re showing up right next to them and saying, ‘Lemonade for free’." I'm just waiting for them to find a way to declare this illegal. Also, free lemonade. They'll declare that illegal too.
