Once a year we release all metadata records for content registered with Crossref in a public data file. This year’s version, containing nearly 180 million records, is now available. It includes metadata associated with all Crossref-registered DOIs in JSON-lines format.
Crossref Ambassadors act as local points of contact, meeting editors, librarians, researchers, and institutions to help them navigate Crossref services and understand how strong metadata supports visibility, integrity, and trust in research. They explain how to participate in our rich network of connections between works, people, and institutions, in ways that make sense in their own contexts. And last year, being our 25th anniversary, Ambassadors also massively contributed to our celebrations!
We have renewed our partnership with DOAJ to focus on a new set of objectives that reflect both organisations’ commitment to improving sustainable and equitable services and infrastructure. This renewed collaboration focuses on improving the quality of scholarly metadata while expanding support for journals in low- and middle income- countries.
We have worked together since 2021, primarily to encourage the dissemination and use of scholarly research using online technologies, and regional and international networks, partners and communities. This partnership has helped to build local institutional capacity and sustainability within the global scholarly communication ecosystem. A continued partnership also reflects that we have a shared community; currently almost 90% of DOAJ journals are represented in Crossref.
With key milestones achieved in 2025, including the appointment of new Directors of Technology and Programs, a move to the cloud, and some key schema updates, we now have a firm foundation for our next challenge: a redesign of our core technical systems to make them more modern, robust, and easier to maintain and scale.
Since we announced last September the launch of a new version of iThenticate, a number of you have upgraded and become familiar with iThenticate v2 and its new and improved features which include:
A faster, more user-friendly and responsive interface
A preprint exclusion filter, giving users the ability to identify content on preprint servers more easily
A new “red flag” feature that signals the detection of hidden text such as text/quotation marks in white font, or suspicious character replacement
A private repository available for browser users, allowing them to compare against their previous submissions to identify duplicate submissions within your organisation
A content portal, helping users check how much of their own research outputs have been successfully indexed, self-diagnose and fix the content that has failed to be indexed in iThenticate.
We’ve received some great feedback from iThenticate v2 users and user testers:
“There are a lot of new and helpful features implemented in version 2 of iThenticate.”
– Beilstein Institut
“The updates to the user interface make working with the new version a pleasure. It has a very modern feel and is easy to use, as an app on a phone. We particularly like being able to click on a link and easily exclude a source from view with just a few clicks. The response time and speed of download are also greatly improved which will cut down processing time on our end.”
– Frontiers
“I like the ability to be able to exclude content directly from the report.”
– American Chemical Society
More information for administrators and users is available on the Turnitin website: iThenticate v2 documentation.
Upgrading to iThenticate v2
In September, we started inviting new and existing Similarity Check subscribers using iThenticate in the browser to upgrade to this new version. And now some of the manuscript submission systems have completed their integrations with the new version of iThenticate too, so users of these systems can start to migrate. Morressier users are already using iThenticate v2, and in the next few days, we will be emailing all eJournalPress users. We know the other major manuscript submission systems are also working on their integrations, and we’ll be in touch with members using them as soon as they confirm they are ready.
Manuscript tracking system integrations
All Similarity Check subscribers using a manuscript management system will particularly appreciate a closer integration with iThenticate v2 which means that users will be able to view their Similarity Report and investigate sources within their manuscript tracking system.
eJournalPress
eJournalPress users will also be able to customise their iThenticate v2 settings via a configuration interface and to decide, for example, to include or exclude bibliographies from their Similarity Reports. The new integration will also show the top five matches returned by iThenticate directly in the eJournalPress interface.

Editorial Manager and ScholarOne
Aries (Editorial Manager) and Clarivate (ScholarOne) are planning to release their iThenticate v2 integrations later this year and we will be inviting users to upgrade in the coming months.
Please check our community forum for updates on manuscript tracking system integrations.

User-friendly PDF report
“The report is clean and easy to read.”
– The National Academies of Sciences, Engineering, and Medicine
“The clickable links will save us a considerable amount of time as they make it easy for the author to understand where the overlap is coming from, meaning we do not need to spend time clarifying overlap reports to the authors. The summary page is also very useful as authors and editors are easily able to see which sections have been included and excluded from the report.”
– Frontiers
The PDF version of the Similarity Report has been completely redesigned and can easily be downloaded, emailed and printed. It contains a summary of the report i.e. word count, character count, number of pages, file size, excluded sections, submission, and report dates as well as the similarity score and a list of the top sources with clickable links.

Custom section exclusion filter
In iThenticate v2, users can now exclude sections that are standard such as authors, affiliations, ethics statements, acknowledgments, etc. from the Similarity Report which often impacts similarity scores. You can choose from the templates available and/or create your own custom section exclusions from the admin portal.

“The user interface is definitely more responsive than v1, especially when I am looking at the full-text viewing mode, scrolling through the text to compare matches, reading through the box of text in the matching source […] I also especially like the options around excluding, I was able to see our submitted work was also taken into the database and showed matches against the papers we’d uploaded already. Going forward, this is a really interesting thing for us, especially if we are looking at duplicated content in the same journal.”
– Taylor & Francis
User reporting
Details of user activity including folder names, similarity scores, word count, and file format are now also available in iThenticate v2 and downloadable as Excel and csv. files.

Product development
Further enhancements to existing features and interface such as the view full-text mode, user groups, and custom section exclusions are planned for this year. Paraphrase detection and citation matching are currently in development.
iThenticate v2 training
iThenticate v2 documentation is available from the Turnitin website. Training videos and webinars will be available later on in the year.
