Since the mid-1990s, the digital repository has become one of the most important medial forms for the publication, distribution, and storage of literary works. Incorporating characteristics of other vital platforms for alternative literary and artistic communities, such as the little magazine, the anthology, and the reading series, the digital repository has impacted the status of what a literary work is, and casts in a new light certain critical terms for poetics. This article focuses on the cultural-technical infrastructures of three prominent repositories related to poetry on the early Web -- the Electronic Poetry Center, UbuWeb, and PennSound. It presents a media-historical overview of each repository’s texts and contexts, with special attention to the materials and protocols involved in their production. By approaching the repositories through the lens of three unique emphases -- access, circulation, and format -- this essay develops a critical methodology for addressing literary production in a networked digital culture.
