Scientific software has been a vital research tool for decades, used in everything from simulations to artificial intelligence. To date, however, no-one has come up with a strategy to collect and preserve these important milestones of digital science. The project “Edition Scientific Software (EWS): Research on History of Science and Philosophy of Science Aspects and Edition of Software History of Digital Sciences from 1950 to 2010” fills this gap. The project explores, documents and edits historical software projects from a wide range of disciplines and makes this information available on an online platform.
