A new interactive documentary called Cold Storage invites viewers to peer beyond Harvard’s flagship Widener Library—the tip of the iceberg in terms of the university’s massive collection—and into the vault where more than 9 million books and artifacts are stored. Gizmodo reports on the viewing experience, describing a world designed for the convenience of the machines in charge of storing and retrieving items, and oddly removed from the typical culture of reverence for books as a category of uniquely valuable objects. Check it out for a glimpse behind the curtain, and perhaps into a certain view of the future of archival libraries.
