This article reviews Cornelia Vismann’s 2008 book Files: Law and Media Technology. In addition to an overview of Vismann’s media materialist approach to the study of the law, it provides both a consideration of her relationship to Friedrich Kittler’s media theory and a more focused examination of certain functional writing entities that might extend Vismann’s genealogical approach. It is suggested that a closer analysis of one such entity, the list, can offer further insight into the epistemological and ontological questions the book provokes.
