Happy Birthday! This Friday (April 6) the Initiative for Open Citations (I4OC) Will Celebrate Its First Birthday

From a Wikimedia Blog Post:

The Initiative for Open Citations (I4OC was publicly launched almost one year ago. To mark the progress that’s been made and to build new momentum, we are designating April 2018 Open Citations Month (hashtag #OpenCitationsMonth). We invite everyone with an interest in open scholarship to get involved so that we can get closer to the goal of 100% open citation data.


One year on, the fraction of open citation data has now surpassed 50% and the number of participating publishers has risen to 490. There are over 500 million references now openly available. Of the top twenty biggest publishers with citation data, all but five now make these data open via Crossref. And there are almost fifty stakeholder organisations who have joined I4OC to help advocate and promote reuse of open citations. The initiative has attracted commentary and media coverage across the world.


This progress has been rapid and has been exciting to witness, but there is still a lot to do. First and foremost, we need to get closer to 100% open citation data. We have learned over the past year that the decision to make references open takes varying amounts of time for different publishers, and we have been in contact with many publishers who are yet to make the positive decision. We hope that the mounting evidence of access and reuse of citation data will soon convince them to make that decision and make public the reference lists from their published articles – essential metadata for open scholarship. In the so-called ‘post-truth’ era, the need for this rigorous and precious information could hardly be greater.
