This chapter intervenes in critical debates about the recording and documenting of histories of the future by critiquing, and offering an alternative approach to, current practices. It argues that many histories of the future rely on an extremely selective range of empirical sources which secure particular versions of, and narratives about, the future. Instead, this chapter identifies and examines the multifarious form of the periodical as a vital source material for reconstructing the past. Juxtaposing numerous techniques of representing the future, the periodical enables different ways of imagining, predicting, and resisting possible futures to collide against and compete with each other in a variety of rapidly shifting contexts. Reading the diversity of modes for presenting futures in periodicals can help us to consider how different representations of the future, with a wide range of temporalities, are woven into one another within ordinary public discourse.
