Contributorship, not authorship: use CRediT to indicate who did what

Abstract

Participation in the writing or revising of a manuscript is, according to many journal guidelines, necessary to be listed as an author of the resulting article. This is the traditional concept of authorship. But there are good reasons to shift to a contributorship model, under which it is not necessary to contribute to the writing or revision of a manuscript, and all those who make substantial contributions to a project are credited. Many journals and publishers have already taken steps in this direction, and further adoption will have several benefi This article makes the case for continuing to move down that path. Use of a contributorship model should improve the ability of universities and funders to identify effective individual researchers and improving their ability to identify the right mix of researchers needed to advance modern science. Other benefi should include facilitating the formation of productive collaborations and the creation of important scientifi tools and software. The CRediT (Contributor Roles Taxonomy) taxonomy is a machine-readable standard already incorporated into some journal management systems and it allows incremental transition toward contributorship.
