(19 Aug 2026) The Contributor Roles Taxonomy, or CrediT, has over the past years clarified how different hands lead to the creation of research papers. Taking stock of the past decade, Andrea Chiarelli, Lucia Loffreda, Liz Allen, Mohammad Hosseini, Sandra Bendiscioli and Holly Ranger consider CrediT’s success and the challenges it faces if it is to become more embedded in funding and research assessment processes.
In 2024, roughly 22 per cent of original research articles, preprints and conference papers with full text on the Dimensions platform carried CRediT information: nearly 850,000 outputs. From this summer, Crossref.org will begin embedding CRediT in version 5.5 of its metadata schema, so that, for the first time, contributions to a paper can be described in the open metadata record rather than flattened into an article byline or lost on the last page of a PDF.
This is a major achievement, but CRediT’s success has been uneven. The initiative has spread the fastest in publishers’ submission systems where authorship data was already being captured. However, in contexts where richer contributor information might actually shift outcomes, such as how funders assess applicants or how universities evaluate researchers, the use of CRediT is much less common.
