Country view

This section shows how hybrid open access has been adopted in different parts of the world. The analysis is based on the country affiliation of lead authors. Lead authors are the first named authors of scholarly articles, who have typically conducted most of the research presented in the article, although the role of lead authors can vary across disciplines. We used OpenAlex as a data source to determine the affiliation of lead authors.

Open metadata

Open and comprehensive metadata is a key requirement of many transformative agreements. The following tables illustrate potential gaps in Crossref metadata for Open Access articles in hybrid journals included in transformative agreements.

License metadata gaps

IOP (TIB): Comparison of open licence metadata in Crossref with Unpaywall via OpenAlex per year. You can compare global metrics with metrics only for articles by lead authors based in Germany. In addition to Crossref licence information, Unpaywall also analyses publisher websites to determine whether an article has been published under an open content licence. More Open Access articles derived from Crossref may indicate a delay between metadata changes and Unpaywall-indexing, while more Open Access articles identified by Unpaywall suggest that publishers have not deposited licensing metadata in Crossref for all articles.
