As Crossref celebrated its 25th anniversary last year, we are highlighting some of the most active and engaged regions in our global community.
Over the past 25 years, the makeup of Crossref membership has evolved significantly; founded by a handful of large publishers, we now have more than 24,000 members representing 165 countries. Nearly two-thirds of them self-identify as universities, libraries, government agencies, foundations, scholar publishers, and research institutions.
It’s been said that Americans are unusual in tending to ask “Where do you work?” as an initial question upon introduction to a new acquaintance, indicating a perhaps unhealthy preoccupation with work as identity. But in the context of published research, “What is this author’s affiliation?” is a question of global importance that goes beyond just wanting to know the name – and perhaps prestige level – of the place a researcher works.
As Crossref membership continues to grow, finding ways to help organisations participate is an important part of our mission. Although Crossref membership is open to all organisations that produce scholarly and professional materials, cost and technical challenges can be barriers to joining for many.
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.
We encourage you to include references (citation lists, bibliographies, data and software citations) with all content you register. A key benefit is that they will appear in Cited-by query results. You can include references when your first register your DOI records, or you can add them to existing DOI records later. Learn more about the benefits of registering your references.
Including references (or adding them to an existing deposit) can be done by:
Crossref XML plugin for OJS: You must first enable References as a submission metadata field and then enable the Crossref reference linking plugin, to include references in your initial deposit, or add them later.
Metadata Manager: Our new Metadata Manager tool (previously known as the record registration form) has a built-in field for adding references. Learn more about how to use this tool.
Simple Text Query allows you to both find the DOIs for your references and add them to the metadata for a DOI that you have already registered with Crossref. Please note that this method will overwrite any references previously deposited for the content item - if you’ve previously added references to an item, and want to add more references using Simple Text Query, you need to include both the existing and the new references in your deposit.
If your details have been entered correctly, you will see a success message, showing that your deposit has been submitted to the system queue for processing. When the reference deposit has been submitted, you will receive an email containing the XML deposit generated by the form. After that submission has been processed (usually within minutes of your submission), you will receive a submission log by email with the results of your submission.
