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.
Itâs been said that Americans are unusual in tending to ask âWhere do you work?â 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, âWhat is this author’s affiliation?â 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.
Test out the early preview of Event Data while we continue to develop it. Share your thoughts. And be warned: we may break a few eggs from time to time!

Want to discover which research works are being shared, liked and commented on? What about the number of times a scholarly item is referenced? Starting today, you can whet your appetite with an early preview of the forthcoming Crossref Event Data service. We invite you to start exploring the activity of DOIs as they permeate and interact with the world after publication.
But first, a bit of background
Discussion around scholarly research increasingly occurs online after publication, for example on blogs, sharing services, social media, and wikis. These âeventsâ occur across the web on numerous platforms and are a critical part of the scholarly enterprise. We are developing an infrastructure service (Crossref Event Data) that collects, stores, and delivers raw data of the events occurring with Crossref DOIs. We will store the data in an open, auditable and portable form for the community to access. Publishers, platforms, funders, bibliometricians and service providers may benefit from access to this raw data, and it can be used to feed into research records or proprietary tools and services that offer aggregation and analysis.
Developers Martin Fenner (DataCite) and Joe Wass (Crossref) enjoy a tofu break
Lagotto, the software originally developed at PLOS, has been extended and improved in a joint effort between DataCite and Crossref. The two DOI Registration Agencies have partnered to envision, build and release the service. On the 13th of April, after a year ofcollaboration, we jointly released Lagotto 5.0. You can read about the collaboration on the DataCite blog post.
Crossref and DataCite will continue to work closely together to develop Lagotto and the Event Data service. Although Crossref Event Data has mostly Crossref DOIs at launch, you will be able to find DataCite DOIs if they are cited in Crossref or Wikipedia.
All of the software that runs Event Data, including Lagotto, is developed in the open and is open source. Please refer to the Crossref Event Data Technical User Guide for full details.
Preview the data
This service is currently under development with a full launch expected the second half of 2016. Before it is launched however, we invite you to take a look around and preview a subset of the data sources we plan to include. You may experience occasional hiccups while we continue building the service.
At this stage, we are working with data from three sources although we will greatly expand the variety of platforms from which we collect data as development progresses. At this stage, you can view Mendeley bookmarks, Wikipedia references, and Crossref to DataCite links.
Mendeley
Mendeley is a reference manager and academic social network for scholars. View the number of social bookmarks from scholars or groups on Mendeley.
Wikipedia is an online encyclopaedia, the Internetâs largest and most popular general reference work. View references in Wikipedia of Crossref publications in Wikipedia articles in all languages.
DataCite is a global consortium that assigns DOIs to research data. This enables people to find, share, use, and cite data. You can view all the data citations to DataCite research outputs found in Crossref publications (work is underway to make the links found in DataCite metadata available in Event Data).Â
You can explore the Crossref Event Data early preview by visiting http://eventdata.crossref.org and following the links to featured examples within our interim application for inspecting the data, technical documentation, and our Quick Start guide.
Share your thoughts
This service is currently under development and as such we welcome your thoughts and feedback on the data we are collecting currently from our three active sources. As a reminder, we expect to include the following sources as part of our full service launch later this year (pending confirmation):

Â
Weâre also on the lookout for new data sources to investigate for future inclusion in the Event Data service so please do get in touch with requests and recommendations. As we continue to build the service throughout 2016, we will be committing to a model of continuous development so that we can make new sources available as they are completed.
