Event Data is our service to capture online mentions of Crossref records. We monitor data archives, Wikipedia, social media, blogs, news, and other sources. Our main focus has been on gathering data from external sources, however we know that there is a great deal of Crossref metadata that can be made available as events. Earlier this year we started adding relationship metadata, and over the last few months we have been working on bringing in citations between records.
Tl;dr: Metadata for the (currently 26,000) grants that have been registered by our funder members is now available via the REST API. This is quite a milestone in our program to include funding in Crossref infrastructure and a step forward in our mission to connect all.the.things. This post gives you all the queries you might need to satisfy your curiosity and start to see what’s possible with deeper analysis. So have the look and see what useful things you can discover.
Update on the outage of October 6th. In my blog post on October 6th, I promised an update on what caused the outage and what we are doing to avoid it happening again. This is that update.
Crossref hosts its services in a hybrid environment. Our original services are all hosted in a data center in Massachusetts, but we host new services with a cloud provider. We also have a few R&D systems hosted with Hetzner.
Looking at the road ahead, we’ve set some ambitious goals for ourselves and continue to see new members join from around the world, now numbering 16,000. To help achieve all that we plan in the years to come, we’ve grown our teams quite a bit over the last couple of years, and we are happy to welcome Carlos, Evans, Fabienne, Mike, Panos, and Patrick.
Reference linking enables researchers to follow a link from the reference list to other full-text documents, helping them to make connections and discover new things.
To link references, you don’t need to be a Crossref member. Reference linking means including Crossref DOIs (displayed as URLs) when you create your citation list. This enables researchers to follow a link from a reference list to other full-text documents, helping them to make connections and discover new things. And because it’s a DOI rather than just a link, it will remain persistent.

Because Crossref is all about rallying the scholarly community to work together, reference linking is an obligation for all Crossref members and for all current journal content (published during this and the two previous years). It is encouraged for other content types (such as books and conference proceedings), and for backfiles (published longer ago).
Watch the introductory reference linking animation in your language:
Persistent links enhance scholarly communications. Reference linking offers important benefits:
Reciprocity: members’ content is linked together and more discoverable because all members link their references.
Crossref acts as a clearinghouse, negotiating reciprocal agreements among all its members so that individual members can avoid the inconvenience of signing bilateral agreements to link to persistent content on other platforms. The result is a scholarly communications infrastructure that enables the exchange of ideas and knowledge.
Discoverability: research travels further when everyone links their references. Because DOIs don’t break if implemented correctly, they will always lead readers to the content they’re looking for, including yours. When the DOIs are displayed, anyone can copy and share them.
This will enable better tracking of where and when people are talking about and sharing scholarly content, including in social media.
Obligations and fees for reference linking
There’s no charge for reference linking but it is an obligation of membership. Reference linking is required for all Crossref members and for all current journal content. We’d encourage you to also add reference linking for backfile journals, and for other content types.
To link references, you do not need to be a member, but reference linking is an obligation for Crossref members. When your organization becomes a Crossref member, look up the DOIs for your references, and add the DOI (as a URL) to reference lists for your content items.
Best practice for reference linking
Start reference linking within 18 months of joining Crossref
Link references for backfile as well as current journal content
Link references in non-journal content types such as books, and conference proceedings.
