Sabina Leonelli’s new book – “Philosophy of Open Science” – will be published later this year. However, there is an open access preprint available on the PhilSci Archive here. In the book, Leonelli provides “a constructively critical reading” of the standard approach to open science which, she argues, is focused on sharing “objects” such as data and materials. In Leonelli’s view, this object-sharing approach has become an obstacle to promoting open science. Grounded in philosophies of science from Popper, Chang, Longino, and others, she puts forward an alternative, process-oriented view of open science that refers to efforts to establish “judicious connections among systems of practice.”
