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.
Once a year we release all metadata records for content registered with Crossref in a public data file. This year’s version, containing nearly 180 million records, is now available. It includes metadata associated with all Crossref-registered DOIs in JSON-lines format.
Crossref Ambassadors act as local points of contact, meeting editors, librarians, researchers, and institutions to help them navigate Crossref services and understand how strong metadata supports visibility, integrity, and trust in research. They explain how to participate in our rich network of connections between works, people, and institutions, in ways that make sense in their own contexts. And last year, being our 25th anniversary, Ambassadors also massively contributed to our celebrations!
We have renewed our partnership with DOAJ to focus on a new set of objectives that reflect both organisations’ commitment to improving sustainable and equitable services and infrastructure. This renewed collaboration focuses on improving the quality of scholarly metadata while expanding support for journals in low- and middle income- countries.
We have worked together since 2021, primarily to encourage the dissemination and use of scholarly research using online technologies, and regional and international networks, partners and communities. This partnership has helped to build local institutional capacity and sustainability within the global scholarly communication ecosystem. A continued partnership also reflects that we have a shared community; currently almost 90% of DOAJ journals are represented in Crossref.
We operate on a budget of around $14 million (USD). About one-third of our revenue comes from annual dues (e.g., membership fees, subscriptions) and two-thirds from services (e.g., Content Registration, Similarly Check document checking). Our fees are set and reviewed by the Membership & Fees committee, which includes our staff, board, and community members. This group also created a set of fee principles which were approved by the board in 2019.
About 70% of our expenses are related to people - staff, benefits, and contracted support. 30% of our costs are everything else - hosting costs, licensing fees, events, and costs to do business like banking fees and insurance.
Each year we strive to generate a small operating net and have been able to do so nearly every year.
We also maintain a reserve fund to support long-term sustainability. We periodically report on our progress towards fulfilling the Principles of Open Scholarly Infrastructure: 2020, 2022, 2024
Below is a look at how our operations have changed over time.
The majority of our revenue comes from members in smallest and largest tiers. We have seen the most growth in revenue from the smallest fee tier.F
Annual financial reporting
As a not-for-profit, we are tax-exempt, and to maintain that status, we undergo a financial audit each year by an independent accounting firm. Our auditors prepare our Form 990, which the US IRS requires and is made publicly available. It gives an overview of what we do, how we are governed, and detailed financial information.
Below are our recent Form 990s and audited financial statements.
