In our editorial launching the new Reproducible Research Track in CiSE \citep*{Barba_2017} , we promised to explore innovations to the peer-review process. Because we require articles submitted to this track to adhere to practices that safeguard reproducibility, we must review for these aspects deliberately. For each submission, a reproducibility reviewer will be charged with checking availability, quality and usability of digital artifacts (data, code, figures). This reviewer (sometimes one of the track editors) will be known to the authors, and may interact with the authors during the review—for example, opening issues on a code repository. For this service, we ask that the authors recognize the reviewer in the article's acknowledgements section.
