Though the phenomenon known as “unreliable narration” or “narrative unreliability” has received a lot of attention during the last two decades, narratological research has mainly focused on its manifestations in narrative fiction, particularly in homodiegetic or first-person narration. Except for film, forms and functions of unreliable narration in other genres, media and disciplines have so far been relatively neglected. The present volume redresses the balance by directing scholarly attention to disciplines and domains that narratology has so far largely ignored. It aims at initiating an interdisciplinary approach to, and debate on, narrative unreliability, exploring unreliable narration in a broad range of literary genres, other media and non-fictional text-types, contexts and disciplines beyond literary studies. Crossing the boundaries between genres, media, and disciplines, the volume acknowledges that the question of whether or not to believe or trust a narrator transcends the field of literature: The issues of (un)reliability and (un)trustworthiness play a crucial role in many areas of human life as well as a wide spectrum of academic fields ranging from law to history, and from psychology to the study of culture.
