From the JISC Scholarly Communication Blog:
OpenDOAR is the quality-assured global directory of academic open access repositories. It enables the identification, browsing and search for repositories, based on a range of features, such as location, software or type of material held.
We’ve been working with our user experience experts and our users to develop a simplified and streamlined website with a more modern, responsive design. The new interface has been designed to work just as well on your smartphone as on your computer.
The current version of the OpenDOAR service, including its API, will be switched off at the end of May 2018.
