 Learn more about IDEAS' progress in the paper *[A cast of thousands: How the IDEAS Productivity project has advanced software productivity and sustainability](https://arxiv.org/abs/2311.02010)*. 
 A webinar video on the same topic, including some lessons learned about software stewardship and discussing some of the possible futures for the HPC/CSE scientific software community can be found on the [IDEAS Productivity website](https://ideas-productivity.org/events/hpcbp-080-ideas) as well.
 
-For some of the motivation of the project, readers can refer to the January 2020 report, [Advancing Scientific Productivity through Better Scientific Software: Developer Productivity and Software Sustainability](https://doi.org/10.2172/1606662), which outlines the IDEAS-ECP project's initial efforts to enhance software productivity and sustainability for extreme-scale computational science and engineering (CSE) as part of the DOE Exascale Computing Project (ECP).

 The target audience for the above materials are all those who care about the quality and integrity of scientific discoveries based on simulation and analysis. 
 While the difficulties of extreme-scale computing intensify software challenges, issues are relevant across all computing scales, given universal increases in complexity and the need to ensure the trustworthiness of computational results.
