Deprecating co-access: Crossref plans and timelines

Isaac Farley

Isaac Farley, Sara Bowman – 2025 September 11

In CommunityBooks

To date, there are about 100 Crossref members who have made use of our co-access service for one or more of their books. The service was designed to be a last-resort measure when multiple parties - book publishers, aggregators, and other members - had rights to register book content. Unfortunately, the service allowed members to register multiple DOIs for shared books and book chapters, thereby violating our own core tenet of one DOI per content item. We should not have created a service that violated that tenet, resulting in duplicate DOIs. As we are able to offer an alternative in the form of the multiple resolution service, it is time to switch co-access off. Among other benefits – for the publisher and the authors, creation of a single DOI for each item, regardless of where it might be hosted, will result in more accurate citation counts and usage statistics. We’re retiring co-access at the end of 2026.

Celebrating one year of Crossref Grant IDs at NWO

This month marks one year since the Dutch Research Council (NWO) introduced grant IDs—an important milestone in our journey toward more transparent and trackable research funding. We created over 1,600 Crossref Grant IDs with associated metadata. We are beginning to see them appear in publications. These early examples show the enormous potential Grant IDs have. They also highlight that publishers could extend their efforts to improve the quality of funding metadata of publications.

An eLife filled with possibility thanks to great metadata

eLife recently won a Crossref Metadata Award for the completeness of its metadata, showing itself as the clear leader among our medium-sized members. In this post, the eLife team answers our questions about how and why they produce such high-quality open metadata. For eLife, the work of creating and sharing excellent metadata aligns with their mission to foster open science and supports their preprint-centred publication model, but it also lays the groundwork for all kinds of exciting potential uses.

From storage closet to metadata champions: ASM’s journey toward a smarter scholarly infrastructure

The American Society for Microbiology (ASM) has earned recognition in Crossref’s Participation Reports for its exceptional metadata coverage among large publishing members––an achievement built on intentional change, technical investment, and collaborative work. In this Q&A, the ASM team shares what that journey looked like, the challenges they’ve tackled, and how centering metadata has helped them better connect research with the global scientific community.

Crossref at Beijing International Book Fair 2025

This June, we presented at the Beijing International Book Fair (BIBF) and connected directly with our growing community in China. With a surge of interest from Chinese publishers and partners, it was clear: there’s a strong and rising curiosity around how metadata plays a vital role in maintaining the integrity of the scholarly record.

As a new Community Engagement Manager at Crossref, dedicated to working with the funders community, I frequently hear requests for examples and case studies of adopting Crossref’s Grant Linking System (GLS) by ‘funders like us’. This has spurred me to start a series of blog posts presenting funders’ perspectives on joining Crossref and using our system – to demonstrate how it’s done. 

Sprinting to Progress: Behind the scenes of our first metadata sprint

If you take a peek at our blog, you’ll notice that metadata and community are the most frequently used categories. This is not a coincidence – community is central to everything we do at Crossref. Our first-ever Metadata Sprint was a natural step in strengthening both. Cue fanfare!. And what better way of celebrating 25 years of Crossref?

We designed the Crossref Metadata Sprint as a relatively short event where people can form teams and tackle short problems. What kind of problems? While we expected many to involve coding, teams also explored documenting, translating, researching—anything that taps into our open, member-curated metadata. Our motivation behind this format was to create a space for networking, collaboration, and feedback, centered on co-creation using the scholarly metadata from our REST API, the Public Data File, and other sources.
