David Carroll, co-lead of the Open Access Button gives an update on the Open Access Button, with some news and plans for the future. The Open Access Button is a bookmarklet that lets users track when they are denied access to research, then search for alternative access to the article. Each time a user encounters a paywall, they simply click the button in their bookmark bar, fill out an optional dialogue box, and their experience is added to a map alongside other users. Then, the user receives a link to search for free access to the article. The Open Access Button hopes to create a worldwide map showing the impact of denied access to research and to push for a more open scholarly publishing system..
