“A forest in Norway is growing.” So begins the cryptic text printed on a certificate for the Future Library, or Framtidsbiblioteket, an artwork by Scottish artist Katie Paterson that, over the span of a century, cumulatively builds a collection of written works viewable only to future generations. Since the project’s beginning, in 2014, one author from across the globe has been invited each year to contribute a piece of writing—anything from a poem to a short story, or a full-length book—which will be held in trust, unread and unpublished, until the year 2114. The certificate, which comes in a limited edition of 1,000, entitles its bearer to a full anthology of all 100 works, which will be printed on paper culled from the Future Library Forest, a grove of 1,000 trees planted by Paterson in 2014 just outside of Oslo, Norway. As the young saplings continue to flourish and mature, so too does the Future Library’s collection.
