Rarely glimpsed by library patrons, the Harvard Depository (HD) is a crucial piece of the university's knowledge-production infrastructure. Located in rural Southborough, Massachusetts, forty minutes from Cambridge by car, it's home to some ten million books, archival papers, films, and other media. Cold Storage is a documentary short produced by metaLAB to document HD and explore its instrumental and metaphorical roles in the university library. Responding to the 1956 film Tout la mémoire du monde, a short film made by legendary Alain Resnais, the documentary is also a kind of index to a media archive of HD's history and technical systems, and a product of a multi-year seminar on library innovation run by metaLAB in Harvard's Graduate School of Design.
