The title of this journal, Transfers, merits explication, as it attempts to engage a multitude of scholarly fields, applications, practices and conceptual frameworks. For us, Transfers invokes the movement of people, things, and information through time and space, but it also applies to the transit of concepts between fields of scholarship. The practices of technology transfer are an example of the former, while the latter can be seen at work when the concept of mobility is used to refer to both social (or “vertical”) mobility and physical (or “horizontal”) mobility. Social mobility, for instance, comes into play when the possession of a car leads to higher status, or when the train compartment becomes a medium of social exchange or the display of social hierarchies rather than simply a vehicle of physical transport. Interdisciplinarity, the key scholarly mode of this journal, always involves the movement of ideas across disciplinary borders, unsettling them in (we think) productive ways. Transfers, in other words, connects adjacent fields of scholarship as much as it connects geographical areas between which technologies move. It is crucial to understand that during this process, people, technologies, concepts, and goods in movement are transformed and transform their environments in turn. This is not an automatic or passive process: as people move, people translate.
