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.Â
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.Â
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
For Reference Linking, you need to find the existing DOIs for each work in your reference list, and then display the DOI for that item in your reference list.
Step 1: Find DOIs for the referenced works.
There are a few different options:
Crossref Reference Linking plugin in the OJS platform - if you’re using the OJS platform, make sure to add and enable the Crossref Reference Linking Plugin. The plugin will use the Crossref API to check against your plain-text references and locate possible DOIs. It will then display the reference lists with DOIs on the article landing page.
Simple Text Query - paste your reference lists into this web form, and it will return matches. This is a manual interface, and is suitable for low-volume querying.
XML API - submit XML formatted according to the query schema section to our system as individual requests or as a batch upload. This method requires API skills, and allows you significant control over your query execution and results.
Step 2: Display the DOIs in your reference lists.
Once you have retrieved the relevant DOIs, display them as URLs in your reference lists (following our DOI display guidelines).
