In this article, we will discuss the preservation of works of Latin American digital literature and the construction of digital archives. Starting from a discussion of the concept of digital literature, we will broach the implications and challenges of digital preservation and archiving, concerning the works we collected for the project "Cartography of Latin American Digital Literature". Finally, we will present ideas and questions which arise from this work related to innovation, digital aesthetics, and the experience of creating an archive of Latin American digital literature in times of impermanence.
