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 time—downwards. 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.

PID strategies are being written around the world right now, and the decisions being made will shape the scholarly record for decades. After 25 years running open scholarly infrastructure—now on behalf of 25,000 members in 167 countries—Crossref has an informed perspective on what those decisions should ideally rest on. Today we’re setting it out in our first position paper: Persistent identifiers in research infrastructure policy: the need for a holistic approach. You can read it online or download the PDF; it’s a 16-minute read.

For many years, PubPub has made it possible for communities to assign DOIs to a range of outputs and component Pubs. Knowledge Futures and Crossref are building together to test the limits of what’s possible for high-volume, high-granularity DOI management. That means fast prototypes, real building, and learning through the process.

Research integrity depends on accurate, complete, and connected metadata. This joint guide from Crossref and DataCite sets out the metadata elements most critical for assessing research integrity—and how all stakeholders can contribute to and benefit from a richer, more trustworthy scholarly record.

Metadata is communication; it can tell a story about research and paint a picture for others to respond to and learn from, across the world and throughout the forthcoming generations. Metadata can feel technical with words like ‘infrastructure’ and ‘schema’, and sometimes, like tech in general, it comes with hyperbole. But metadata really is part art (storytelling and pictures) and part science (structured models and standards) with both aspects being equally important, and requiring people as well as systems. That necessary combination of human and machine involvement also makes metadata challenging.

We are pleased to announce that—effective 1st January 2026—we have made two changes to grant record registration fees that aim to accelerate adoption of Crossref’s Grant Linking System (GLS) and provide a two-year window of opportunity to increase the number and availability of open persistent grant identifiers and boost the matching of relationships with research objects.

Crossref’s 2025 Annual Report, published as a blog post with a DOI rather than a standalone designed PDF. Covers the year’s governance, finances, programmes, and community highlights. Issued with DOI 10.64000/hsdpk-8cm70.

As we finish celebrating our 25th anniversary, we can look back on a truly transformational year, defined by the successful delivery of several long-planned, foundational projects—as well as updates to our teams, services, and fees—that position Crossref for success over the next quarter century as essential open scholarly infrastructure. In our update at the end of 2024, we highlighted that we had restructured our leadership team and paused some projects. The changes made in 2024 positioned us for a year of getting things done in 2025. We launched cross-functional programs, modernised our systems, strengthened connections with our growing global community, and streamlined a bunch of technical and business operations while continuing to grow our staff, members, content, relationships, and community connections.

In January 2026, our new annual membership fee tier takes effect. The new tier is US$200 for member organisations that operate on publishing revenue or expenses (whichever is higher) of up to US$1,000 annually. We announced the Board’s decision, making it possible in July, and––as you can infer from Amanda’s latest blog––this is the first such change to the annual membership fee tiers in close to 20 years!
