Outsider Literature refers to works created by authors who exist outside mainstream literary circles, often due to their unconventional backgrounds or perspectives. These writers may include those from marginalized communities, self-published authors, or individuals who reject traditional publishing norms. Their works often challenge societal norms and explore themes of alienation, identity, and personal experience. This genre can encompass various forms, including poetry, novels, and essays, and is characterized by its raw, authentic voice. Notable examples of Outsider Literature include the writings of Henry Darger, David Foster Wallace, and Charles Bukowski, who each offer unique insights into the human experience through their distinct styles.
