Lab on a Chip introduces optional authorship contributions to increase transparency

Lab on a Chip is introducing recommended authorship contributions in all its published articles from February 2018.

Including a description of author contributions increases transparency of who contributed what to the article and ensures that each author is given the appropriate level of credit (and responsibility) for their contribution. Inclusion of author contributions is already common practice in many biomedical/life sciences journals.

Authors are strongly encouraged to include with their submitted manuscript a section called “Author Contributions”, which will be published with the final article. Contributions should be explained concisely. Authors are strongly encouraged to use the CRediT taxonomy to describe those contributions (see terms below). Authors should have agreed to their individual contributions ahead of submission and should accurately reflect contributions to the work. Please note that for any manuscript with more than 10 co-authors, the corresponding author must provide the editor with a statement to specify the contribution of each author.

CRediT (Contributor Role Taxonomy) is a taxonomy tool by CASRAI (Consortia Advancing Standards in Research Administration) and it was developed to increase transparency in contributions by researchers to scholarly publications. More information about CRediT can we found on the CASRAI website.
