The emergence of a new phenomenon – digital literature – within the field of literary studies calls for the reorganization and creation of new theoretical and analytical repertoires. Since digital literature partakes of literary tradition as well as introduces critical medial and conceptual innovations that challenge the very concept of literary frontiers and spaces, its scholarly analysis demands significant reformulations in literary studies. As models of communication change, so do the reception and production processes accompanying these changes. Within these altered scenarios, the thesis Digital Literature: Theoretical and Aesthetic Reflections is a response to the aesthetic and theoretical challenges brought on by computer-based literature. As a methodological strategy, the thesis articulates recent trends in the theory of digital aesthetics – remediation (BOLTER), eventilization (HAYLES), correlations of performativity, intermediality and interactivity with meaning-driven analysis (SIMANOWSKI), Medienumbrüche (GENDOLLA and SCHÄFER) – with theories of production of presence (GUMBRECHT), autopoietic communicative models (LUHMANN) and closereadings of digital works. By scripting a dialogue with key theorists from print literary theory as well as new media theorists and artists in the burgeoning field, the thesis offers conceptual and theoretical contributions to the formulation of a poetics of new media.
