We know that software is important in research, and some of us in the scholarly communications community, for example, in FORCE11, have been pushing the concept of software citation as a method to allow software developers and maintainers to get academic credit for their work: software releases are published and assigned DOIs, and software users then cite these releases when they publish research that uses the software.
DOIs created for software is growing roughly exponentially, now reaching about 2000 software DOIs per month, with spikes of around 4000 per month in some of 2017.
As of May 16, 2018, 58,301 DOIs have been registered for software. We can break down this number by repository where the software source code is hosted – most DOIs for software have been registered at Zenodo.
We see a nice exponential growth in the number of DOIs for software, and we don’t expect this to change in 2018 and beyond.
