Richard Cahan and Michael Williams’s CityFiles Press has so far published two gorgeous hardcover photo collections that delve into Chicago history: Edgar Miller and the Handmade Home and Richard Nickel’s Chicago: Photographs of a Lost City. The latest offering, The Lost Panoramas: When Chicago Changed Its River and the Land Beyond, documents the reversal of the Chicago River—aka, “the eighth wonder of the world.” The 175 duotone photos included in Lost Panoramas were culled from thousands of glass-plate negatives discovered by chance in the basement of the James C. Kirie Water Reclamation Plant in Des Plaines. In September CityFiles will publish another book of lost-and-found photographs, this one containing some of the 100,000 street snaps taken by Vivian Maier over the course of four decades living all but unnoticed in Chicago.
