By drawing upon aspects of critical geography to explore three writers' representations of urban space and subject formation, American Ethni/Cities develops and advocates for a new methodological approach to the study of literature. Predicated on theories devised by Henri Lefebvre, David Harvey, Kevin Lynch, Gil Valentine and other geographically-minded thinkers, this spatially conscious literary practice has the potential to enhance one's understanding of literary texts, power dynamics, identity construction, and the spaces we inhabit. By focusing on Cahan's representation of Jewish immigrants living on the Lower East Side of Manhattan, Wright's depiction of black migrants adjusting to life in the industrial North, and Baldwin's exploration of masculinity as a socio-spatial construct, each respective case-study draws attention to the relationship between spatial production and subject formation. The overarching hope of American Ethni/Cities is that others will find this inter-disciplinary partnership productive and will subsequently employ it themselves to further elucidate how the spaces we create, create the people we become.
