ABSTRACT The following article provides a brief overview on the current state of institutional archival practices of social media content and explores some of the key challenges the field continues to face. Social media use has developed into the leading means of human communication in the world, with billions of people utilizing multiple platforms on a daily basis to both document their individual lives and forge digital communities around various interests. Users generate exorbitant amounts of ephemeral content in the form of text, photos, videos and more across multiple platforms which are, by design, unarchivable. As a result, libraries, archives, and other cultural preservation institutions have struggled to find the proper technological tools to capture the sheer amount of data being generated, while also grappling with a variety of methodological, ethical and legal questions that the practice raises. All the while, the amount of social media data containing potentially important cultural heritage artifacts of our time continues to grow and remain at risk of being forever lost, altered or altogether erased. This article looks at several notable examples of major social media data loss that have already taken place in recent history and examines one of the largest institutional attempts to preserve social media thus far in the Library of Congress’ Twitter Archive. By exploring some of the key challenges that arose during this attempt which ultimately grounded the project, this article aims to better understand what continues to keep the practice of social media archiving at bay, and what large scale changes might be necessary to make any further progress in the field.
