After cataloguing John Berger's archive at the British Library, Tom Overton spent fifteen years following its traces from Moscow to Texas, from the Alps to Istanbul. He worked with Berger on editing Portraits: John Berger on Artists and Landscapes: John Berger on Art, with Matthew Harle on The Underground Sea: John Berger on Miners and the Miners' Strike, and with Katya Berger on a forthcoming edition of Berger's letters. He's written for The Guardian, New Statesman, Frieze and London Review of Books and Paris Review blogs, works as the Archive Curator of the Barbican Centre, and lives in Sheffield.
