This is volumethree in a four-volume edition of primary source materials that document the histories of design across the long nineteenth-century. Each volume is arranged by appropriate sub-themes and it is the first set of primary sources to be gathered together in this comprehensive and accessible format. Design refers to more than simply products and personalities or even cultural ideas, it involves consideration of ways of design thinking and applications as well as the philosophies and the other disciplines that impinge upon it. Here, the third volume considers the issues of design production and practices including debates about the role of machine and craft, the impact of new materials and technologies as well as issues of marketing and mediation. The volumes will be of interest to a range of scholars and students, including those in art and design history, visual culture, and nineteenth-century material culture. They will also be of interest to a broad range of scholars working in areas including aesthetics, gender, politics, and philosophy.
