On 9th January 2018, I published a World View article in Nature entitled Funders should mandate open citations , in which I argue that access to open references from scholarly publications is so important that, when encouragements from organisations such as the Initiative for Open Citations (I4OC) to publishers to open their references fall on deaf ears, then sterner measures are required.
Specifically, major funders should extend their open access mandates and require grant recipients to publish only in journals whose publishers ensure their references are open.
This suggestion was originally made by Catriona MacCallum, Director of Open Science at Hindawi, during a recent I4OC conference call, and she deserves the credit for it.
