Reference lists for more than 60 million journal studies in Crossref are now free to view and reuse.
(13 Sep 2022) The more than 60 million scientific-journal papers indexed by Crossref — the database that registers DOIs, or digital object identifiers, for many of the world’s academic publications — now contain reference lists that are free to access and reuse.
The milestone, announced on Twitter on 18 August, is the result of an effort by the Initiative for Open Citations (I4OC), launched in 2017. Open-science advocates have for years campaigned to make papers’ citation data accessible under liberal copyright licences so that they can be studied, and those analyses shared. Free access to citations enables researchers to identify research trends, lets them conduct studies on which areas of research need funding, and helps them to spot when scientists are manipulating citation counts.
