ISTL has adopted the authorship statement drafted by McNutt et al. (2018):

“Each author is expected to have made substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data; or the creation of new software used in the work; or have drafted the work or substantively revised it; AND to have approved the submitted version (and any substantially modified version that involves the author’s contribution to the study); AND to have agreed both to be personally accountable for the author’s own contributions and to ensure that questions related to the accuracy or integrity of any part of the work, even ones in which the author was not personally involved, are appropriately investigated, resolved, and the resolution documented in the literature” (p.25).

When there is an unresolved question about authorship or competing interests in a submitted paper, the editors will delay the review and production processes until a satisfactory resolution of all unresolved issues has been reached.

Works submitted for publication must not have been previously published in other venues nor be concurrently submitted elsewhere for publication. Manuscripts that derive from material previously presented at conferences may be considered if they have been substantially revised.

Co-First Authorship

When authors of a submission request co-first authorship, column editors will indicate this by adding an asterisk after each author name on the galley with a note below the author names that states “*co-first authors, all subsequent authors equally contributed and listed alphabetically.” Contributor Roles may be further defined if needed using the CRediT definitions. In addition, this information may be added to an Authors’ Contributions section in the manuscript. Contributions to the work that do not meet the criteria of Authorship as defined by CRediT may be indicated in an Acknowledgements section.
