Indexing the great ledger of the community: urban house numbering, city directories, and the production of spatial legibility

Despite the recent focus on the spatial politics of calculation, few studies have explored the historical geography of house numbering, a spatial practice that has arguably been one of the principal strategies for rationalizing the geographic spaces of everyday life over the course of the last two centuries. This paper provides the beginnings of a critical spatial history of street and house numbering in the gridded cities of the United States since the eighteenth century. City directory publishers were among the leading proponents of numbering houses at a time when many local governments had yet to firmly commit to systematic house numbering as an essential responsibility of the local state. I therefore examine the connection between the publishing of city directories and the development of urban house numbering systems, both of which were integral to the production of spatial legibility and the individualization of the urban population. The notion of viewing the city as a ‘text’ is historicized through a critical analysis of the modernist comparison of urban space to a recordkeeping book. The paper concludes by tracing the institutionalization of house numbering as a practice of spatial governmentality.
