Since the seventeenth century our ideas of scientific authorship have expanded and changed dramatically. In this ambitious volume of new work, Mario Biagioli and Peter Galison have brought together historians of science, literary historians, and historians of the book. Together they track the changing nature and identity of the author in science, both historically and conceptually, from the emergence of scientific academies in the age of Galileo to concerns with large-scale multiauthorship and intellectual property rights in the age of cloning labs and pharmaceutical giants. How, for example, do we decide whether a chemical compound is discovered or invented? What does it mean to patent genetic material? Documenting the emergence of authorship in the late medieval period, authorship's limits and its fragmentation, Scientific Authorship offers a collective history of a complex relationship.
