Un(Controlled) Vocabulary is a blog post written by Alex Custodio and Michael Iantorno that discusses some of the challenges in cataloguing the Residual Media Depot's collection of home computing technologies. How do you label a console that doesn't have a consistent name? Why have certain consoles been relegated to footnotes in videogame histories? And what sorts of metadata are useful for media historians? These working notes discuss some of these provocations and showcase some of the Depot's more interesting holdings.
