Digital poetry is a rapidly developing genre in the arts, marked by the most recent developments in media technology. Illustrating and reflecting the use of languages and sign systems in the symbol machine computer and in digital networks, digital poetry denotes creative, experimental, playful, or even critical language art via programming, multimedia, animation, interactivity, and net communication. P0es1s features contributions to an international symposium at Erfurt University that vividly explore changes in the notions of text and poetry, reception and authorship. Essays, manifestoes, and detailed analyses by researchers and artists make for a fundamental handbook, introducing this new art and illustrating its present state of discourse. This book is published on the occasion of the first extensive exhibition featuring international positions of digital poetry in installations as well as Internet and CD-ROM productions.
