For many years, PubPub has made it possible for communities to assign DOIs to a range of outputs and component Pubs. Knowledge Futures and Crossref are building together to test the limits of what’s possible for high-volume, high-granularity DOI management. That means fast prototypes, real building, and learning through the process.
Last September, we announced we’d be deprecating co-access and encouraging its ~100 users to use our multiple resolution service. We announced that no new DOIs will be placed in co-access from 1st of July 2026 and that the ensuing 6 months should be spent cleaning up records already in co-access and moving them over to multiple resolution.
We’re here with a reminder: co-access is being deprecated…and with an update: To help with the transition to multiple resolution, we offer a tool that simplifies the process and documentation about how to set up multiple resolution.
We’ve recently reached an important milestone for the research nexus: the works in our metadata corpus are now connected with over 2 billion citation links! This is a great opportunity to share a dedicated dataset and discuss why these are important for science.
The Crossref Nominating Committee is inviting expressions of interest to join the Board of Directors of Crossref for the term starting in January 2027. The committee will gather responses from those interested and create the slate of candidates that our membership will vote on in an election in September.
Expressions of interest will be due Monday, June 22, 2026

These LINK tags are placed in the document HEAD section and could be used by crawlers and agents to recognize the work represented by the current document. This sounds like a great idea and we’d like to hear feedback on it.
Concurrently at Nature we have also been considering how best to mark up in a machine-readable way DOIs appearing within a document page BODY. Current thinking is to do something along the following lines:
which allows the DOI to be presented in the preferred Crossref citation format (doi:10.1038/nprot.2007.43), to be hyperlinked to the handle proxy server (<a href="http://dx.doi.org/10.1038/nprot.2007.43">http://dx.doi.org/10.1038/nprot.2007.43</a>), and to refer to a validly registered URI form for the DOI (info:doi/10.1038/nprot.2007.43). Again, we would be real interested to hear any opinions on this proposal for inline DOI markup as well as on Leigh’s proposal for document-level DOI markup.
(Oh, and btw many congrats to Leigh on his recent promotion to CTO, Ingenta.)
