Visualizing freely available citation data using VOSviewer

"Today we released version 1.6.6 of our VOSviewer software for constructing and visualizing bibliometric networks. The most important new feature in this version is the support for working with Crossref data. Recently, the Initiative for Open Citations (I4OC) managed to convince a large number of scientific publishers to make the reference lists of publications in their journals freely available through Crossref. Thanks to I4OC, Crossref has become a valuable data source for VOSviewer users. In this blog post, we discuss how users of the new version 1.6.6 of VOSviewer can benefit from Crossref data."
