As we finish celebrating our 25th anniversary, we can look back on a truly transformational year, defined by the successful delivery of several long-planned, foundational projects—as well as updates to our teams, services, and fees—that position Crossref for success over the next quarter century as essential open scholarly infrastructure. In our update at the end of 2024, we highlighted that we had restructured our leadership team and paused some projects. The changes made in 2024 positioned us for a year of getting things done in 2025. We launched cross-functional programs, modernised our systems, strengthened connections with our growing global community, and streamlined a bunch of technical and business operations while continuing to grow our staff, members, content, relationships, and community connections.
Crossref turned twenty-five this year, and our 2025 Annual Meeting became more than a celebration—it was a shared moment to reflect on how far open scholarly infrastructure has come and where we, as a community, are heading next.
Over two days in October, hundreds of participants joined online and in local satellite meetings in Madrid, Nairobi, Medan, Bogotá, Washington D.C., and London––a reminder that our community spans the globe. The meetings offered updates, community highlights, and a look at what’s ahead for our shared metadata network––including plans to connect funders, platforms, and AI tools across the global research ecosystem.
In my latest conversations with research funders, I talked with Hannah Hope, Open Research Lead at Wellcome, and Melissa Harrison, Team Leader of Literature Services at Europe PMC. Wellcome and Europe PMC are working together to realise the potential of funding metadata and the Crossref Grant Linking System for, among other things, programmatic grantee reporting. In this blog, we explore how this partnership works and how the Crossref Grant Linking System is supporting Wellcome in realising their Open Science vision.
In January 2026, our new annual membership fee tier takes effect. The new tier is US$200 for member organisations that operate on publishing revenue or expenses (whichever is higher) of up to US$1,000 annually. We announced the Board’s decision, making it possible in July, and––as you can infer from Amanda’s latest blog––this is the first such change to the annual membership fee tiers in close to 20 years!
The new fee tier resulted from the consultation process and fees review undertaken as part of the Resourcing Crossref for Future Sustainability program, carried out with the help of our Membership and Fees Committee (made up of representatives from member organisations and community partners). The program is ongoing, and the new fee tier, intended to make Crossref membership more accessible, is one of the first changes it helped us determine.
To work out which version you’re on, take a look at the website address that you use to access iThenticate. If you go to ithenticate.com then you are using v1. If you use a bespoke URL, https://crossref-[your member ID].turnitin.com/ then you are using iThenticate 2.0.
Within a folder, the Documents tab shows all the submitted documents for that folder.
Each document submitted generates a Similarity Report after the document has been through the Similarity Check. If more documents are present than can be displayed at once, the pages feature will appear beneath the documents - click the page number to display, or click Next to move to the next page of documents.
zip file upload - to submit a zip file containing multiple documents, up to a maximum of 100MB or 1,000 files. Larger files may take longer to upload
cut & paste - to submit text directly into the submission box. Use this to copy and paste a submission from a file format that is not supported. This method supports plain text only (no images or non-text information)
iThenticate currently accepts the following file types for document upload:
Microsoft Word® (.doc and .docx)
Word XML
plain text (.txt)
Adobe PostScript®
Portable Document Format (.pdf)
HTML
Corel WordPerfect® (.wpd)
Rich Text Format (.rtf)
Each file may not exceed 400 pages, and each file size may not exceed 100 MB. Reduce the size of larger files by removing non-text content. You can’t upload or submit to iThenticate files that are password-protected, encrypted, hidden, system files, or read-only.
.pdf documents must contain text - if they contain only images of text, they will be rejected during the upload attempt. To check, copy and paste a section of the .pdf into a plain-text editor such as Microsoft Notepad® or Apple TextEdit®. If no text is copied over, the selection does not contain text.
To convert scanned images of a document, or an image saved as a .pdf, use Optical Character Recognition (OCR) software to convert the image to text. The conversion software can introduce errors, so manually check and correct the converted document.
Some document formats can contain multiple data types, such as text, images, embedded information from another file, and formatting. Non-text information that is not saved directly within the document will not be included in a file upload, for example, references to a Microsoft Excel® spreadsheet included within a Microsoft Office Word® document.
Use a word-processing program to save your file as one of the accepted types listed above, such as .rtf or .txt. Neither file type supports images or non-text data within the file. Plain text format does not support any formatting, and rich text format allows only limited formatting.
When converting a file to a new format, save it with a different name from the original, to avoid accidentally overwriting the original file. This is especially important when converting to plain text or rich text formats, to prevent permanent loss of the original formatting or image content of the file.
