The history of human interaction around the globe with its extraordinary mobility, hostility, productivity and creativity has clearly been driven as much by the infringement of borders as by their maintenance. This collection of essays scrutinizes the functions of borders, demarcations and their transgression in literature and other cultural artefacts. This resolutely interdisciplinary volume straddles a number of literary domains and also celebrates intermedial and generic transgressions, with its own internal borders being inhabited by a photo essay and two cycles of poems by contemporary Australian poets. These disciplinary and artistic border-crossings index a fundamental mobility, whether geographical, cultural or intellectual, which provides the very grounds upon which the volume’s critical undertaking reposes.
