We’re sharing a preview from another podcast, The Last Archive. The Last Archive is a show about the history of truth -- or the lack thereof. It's about how we've arrived at the current "fake news" moment. And it's about how we know what we know, and why it seems, these days, as if we can't agree on anything at all. Harvard historian Jill Lepore uncovers the secrets of the past the way a detective might. In this preview, Jill explores some of the roots of human knowledge: the encyclopedia and how the idea of it has grown to information sharing via sites like Wikipedia.
