This year’s edition of the FORCE11 conference was hosted in June by Singapore Management University. Its title, âTo Go Far, Go Together: Advancing Scholarly Communication Across Boundaries and Disruptionsâ truly resonates with Crossrefâs truths; it takes a village! Crossref only works as long as the scholarly research community wants to work together globally, across all disciplines, for integrity and openness of the scientific record. The conversations were influenced by a genuinely diverse mix of librarians, researchers, open infrastructures, and service providers, and that mix shaped almost every interaction we had at the conference.
We have some rather unusual news to share: Crossref fees are going down again. At its meeting in Paris earlier this month, the Crossref Board approved two further recommendations from the Resourcing Crossref for Future Sustainability (RCFS) project: effective 1st January 2027, we will reduce the majority of Content Registration fees for all 25,000 members, and remove fees for back-year records altogether.
Content Registration fees haven’t increased in around 20 years, and this is the first significant change to them in that timeâdownwards. Since these fees account for the largest share of Crossref’s revenue (around 60%), and since every member registers DOI records, these changes reach further than anything we’ve announced under the RCFS project so far.
The infrastructure that registers and distributes Crossref metadata has been running and growing for more than two decades. It now does considerably more than it was built to do, and it shows: two large, tightly coupled monoliths (Content System and REST API), where a change in one place risks breaking something in another.
In its July meeting, the Crossref board approved the use of Crossref surplus funds for a three-year project to accelerate the redesign of the Crossref system. Our plan is to use $1.6 million a year for three years (~USD $4.9M in total) from our surplus funds, which will help us set up a modern infrastructure consisting of separate services for the different functionalities that the Crossref system offers.
In December 2026, we plan to publish new Crossref Member Practices which will set out the standards we expect all Crossref members to meet. From August to October 2026 we are consulting with our members on a draft of these Member Practices. This blog provides the background to this, and explains how you can share your views.
Registering your DOI records using the OJS platform
In order to register DOI records with Crossref, you need to set up your OJS (Open Journal Systems) platform to create DOIs on your Crossref DOI prefix, and also set up your OJS platform to send your records to Crossref. You do this in a different way depending on whether you are using OJS 3.4 or OJS 3.3:
You can download the newest versions of OJS in the Public Knowledge Project’s (PKP) documentation.
Additional OJS plugins for Crossref
There are also other important plugins that can be enabled in OJS to enrich your metadata records:
Funding Metadata plugin - as of OJS 3.1.2, it is possible to enable a funder registry plugin for submitting funding information to Crossref. The plugin will use the Open Funder Registry to check against existing funding agencies. The plugin will include funding information in your Crossref DOI deposits.
Similarity Check plugin - if you are using OJS 3.1.2 or above, you are able to use the Similarity Check plugin. This will enable you to automatically send manuscripts to your iThenticate account to check their similarity to already published content. You will need to be subscribed to Crossrefâs Similarity Check service for this to work.
ROR plugin - the ROR Plugin for OJS enables authors to add the ROR ID for the organization they are affiliated with.
Getting help with OJS plugins
The team at Crossref didnât create these plugins - they were either created by the team at PKP, or by third-party developers. Because of this, we arenât able to give in-depth help or troubleshooting on problems with these plugins.
