JOSS may not solve all of the challenges affecting software sustainability8,9, but it provides an effective approach to addressing the central issue of scholarly credit for research software. We have also partnered with other publishers10 to provide a platform for software publications to be reviewed in tandem with domain publications that use the software. We welcome similar arrangements with other publishers and journals, which would allow authors to submit their software to JOSS as a companion publication to their articles. We also join Nature Methods editors in calling on authors to cite the software they use in their research.
