Wait a bit! Why do we care about software preservation?

Research software is now ubiquitous, but we're still bad at storing and sharing it to enable reuse and reproducibility. In this keynote talk for the Jisc Software Preservation Invitational Workshop on "Making Research Reproducible: Software Preservation, What’s Been Done, What’s Possible, What’s Needed", I'll talk about some of the work that the Software Sustainability Institute and others have done on improving software preservation.
