This article historicizes the archive as a mechanism of exclusion. It focuses on three archival sites (the development of archival rationalization in the 19th century, national archives and the collecting of government documents, and the discipline of history) to analyze their shared logics of classification, identity, evidence, and authenticity. These three sites are connected through the author's attempts to research and write a history of the passport within cultural studies. The archive, therefore, provides a site from which to clarify what is at stake in the claims of cultural studies to be an interdisciplinary project.
