Each organization in the global community of Crossref members (that’s currently over 24k organizations in 166 different countries) plays a key role in building the Research Nexus. Any opportunity we have to meet with our members in person is a highlight and a way for us to learn more from each other. The month of January saw three of us travel to Bangkok to attend the first-ever Charleston Conference organised in Asia and to meet with our growing community in Thailand.
This year, we placed a spotlight on the Latin American community, hosting the second Crossref Metadata Sprint in São Paulo, Brazil from 4 - 6 March 2026. In our first tri-lingual event, we brought together 31 participants from Argentina, Brazil, Colombia, Ecuador, and Mexico. Our goal was to foster community co-creation using the open scholarly metadata. The Sprint was an opportunity to pose questions, share ideas, collaborate on research, and propose innovative solutions that enhance the use of metadata in scholarly communication and beyond.
Read on for more details about the content of the Sprint, and the resulting projects. You can also register to join our Sprint Showcase call on 22nd April to hear directly from the team about their creations.
On 17 March 2026, we experienced an outage that affected DOI resolution for Crossref DOIs and the deposit of metadata records by Crossref members. In this summary, we outline what happened, the impact on our community, and the steps we are taking to strengthen our systems and processes as a result.
We’re excited to announce a new data citation API endpoint and are seeking your feedback. The new service makes existing data citation relationships in our metadata available, thereby surfacing this part of the research nexus. At the same time, we’ve decided that it’s time to move on from Event Data.
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).
