As costs for academic journals stay high, universities look to open access - CUP Newswire

Green open access means that an author’s final draft is made public via online article depositories, though the article may still be published in a subscription journal. Gold open access means the article is published in an open access journal where all content is freely accessible. About 25 per cent of researchers globally take the green route. “How do we fast-forward this to 100 per cent? It’s clear how to do it — you have to mandate green,” said Harnad, who has been advocating open access models since 1989.
