Current scientific research almost always requires collaboration among several (if not several hundred) specialized researchers. When scientists co-author a journal article, who deserves credit for discoveries or blame for errors? How should scientific institutions promote fruitful collaborations among scientists? In this book, leading philosophers of science address these critical questions. [T]he volume exemplifies the kind of careful work which manages to simultaneously be rigorous and philosophically interesting. ... the editors are to be commended for collecting a highly focused, original, and engaging volume. All of the essays address the topic in distinctive ways, and I would be hard pressed to pick any as especially stronger than the others. Philosophers of science and social epistemologists will find this collection highly rewarding.
