2022 public data file of more than 134 million metadata records now available

In 2020 we released our first public data file, something we’ve turned into an annual affair supporting our commitment to the Principles of Open Scholarly Infrastructure (POSI). We’ve just posted the 2022 file, which can now be downloaded via torrent like in years past. We aim to publish these in the first quarter of each year, though as you may notice, we’re a little behind our intended schedule. The reason for this delay was that we wanted to make critical new metadata fields available, including resource URLs and titles with markup.

Do you want to be a Crossref Ambassador?

A re-cap We kicked off our Ambassador Program in 2018 after consultation with our members, who told us they wanted greater support and representation in their local regions, time zones, and languages. We also recognized that our membership has grown and changed dramatically over recent years and that it is likely to continue to do so. We now have over 16,000 members across 140 countries. As we work to understand what’s to come and ensure that we are meeting the needs of such an expansive community, having trusted local contacts we can work closely with is key to ensuring we are more proactive in engaging with new audiences and supporting existing members.
