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.
Learn more about conflicts and the conflict report. Conflicts are usually flagged upon deposit, but sometimes this doesn’t happen, creating a missed conflict.
A missed conflict may occur for several reasons:
Two DOIs are deposited for the same item, but the metadata is slightly different (DOI A deposited with an online publication date of 2011, DOI B deposited with a print publication date of 1972)
DOIs were deposited with a unique item number. Before 2008, DOIs containing unique item numbers (supplied in the <publisher_item> element) were not checked for conflicts.
The missed conflict report compares article titles across data for a specified journal or journals. To retrieve a missed conflict report for a title:
The missed conflict interface will pop up in a second window. Enter your email address in the appropriate field. Multiple title IDs can be included in a single request if needed
A report will be emailed to the email address you provided. This report lists all DOIs with identical article titles that have not been flagged as conflicts.
