The Simulmatics Corporation, launched during the Cold War, mined data, targeted voters, manipulated consumers, destabilized politics and disordered knowledge --- decades before Facebook, Google and Cambridge Analytica. Jill Lepore, the bestselling author of THESE TRUTHS, came across the company’s papers in MIT’s archives and set out to tell this forgotten history, the long-lost backstory to the methods --- and the arrogance --- of Silicon Valley.

The American experiment rests on three ideas --- "these truths," Jefferson called them --- political equality, natural rights and the sovereignty of the people. And it rests, too, on a fearless dedication to inquiry, Jill Lepore argues, because self-government depends on it. But has the nation, and democracy itself, delivered on that promise? THESE TRUTHS tells this uniquely American story, beginning in 1492, asking whether the course of events over more than five centuries has proven the nation’s truths, or belied them. To answer that question, Lepore traces the intertwined histories of American politics, law, journalism and technology.

Digging through archives all over the country, New Yorker staff writer and Harvard historian Jill Lepore unearthed evidence that “The Oral History of Our Time” did in fact once exist. Relying on letters, scraps, and Gould’s own diaries and notebooks --- including volumes of his lost manuscript --- Lepore argues that Joe Gould’s real secret had to do with sex and the color line, with modernists’ relationship to the Harlem Renaissance, and, above all, with Gould’s terrifying obsession with the African American sculptor Augusta Savage. In ways that even Gould himself could not have imagined, what Gould wrote down really is a history of our time: unsettling and ferocious.

Aside from Superman and Batman, no superhero has lasted as long or commanded so vast and wildly passionate a following as Wonder Woman. Like every other superhero, Wonder Woman has a secret identity. Unlike every other superhero, she also has a secret history. Harvard historian and New Yorker staff writer Jill Lepore has uncovered an astonishing trove of documents, including the never-before-seen private papers of William Moulton Marston, Wonder Woman’s creator.

Making use of an astonishing cache of little-studied material, including documents, objects, and portraits only just discovered, Jill Lepore brings Jane Franklin to life in a way that illuminates not only this one extraordinary woman but an entire world.
