Underreporting of matched references in Crossref metadata

In APISCitationMetadata

TL;DR

About 11% of available references in records in our OAI-PMH & REST API don’t have DOIs when they should. We have deployed a fix, but it is running on billions of records, and so we don’t expect it to be complete until mid-April.

Note that the Cited-by API that our members use appears to be unaffected by this problem.

How Crossref metadata is helping bring migration research in Europe under one roof

Conflict, instability and economic conditions are just some of the factors driving new migration into Europe—and European policy makers are in dispute about how to manage and cope with the implications. Everyone agrees that in order to respond to the challenges and opportunities of migration, a better understanding is required of what drives migration towards Europe, what trajectories and infrastructures facilitate migration, and what the key characteristics of different migrant flows are, in order to inform and improve policy making.

Changes to the 2018 membership agreement for better metadata distribution

We are making a change to section 9b of the standard Crossref membership agreement which will come into effect on January 1, 2018. This will not change how members register content, nor will it affect membership fees in any way. The new 2018 agreement is on our website, and the exact wording changes are highlighted below. The new membership agreement will automatically replace the previous version from January 1, 2018 and members will not need to sign a new agreement.
