"Scholars of the Gilded Age and Progressive Era, along with graduate and undergraduate students, will fine A Companion to the Golded Age and Progressive Era, edited by Christopher McKnight Nichols and Nancy C. Unger, an essential resource. The thirty-four essays contained within it, arranged in eight thematic sections are authored by a combination of the field's leading scholars and its rising stars. These pieces range from good to excellent. Overall, this volume combines a profound appreiation for the historians who have long defined this period...with a commitment to moving beyond the belief in American exceptionalism that, consciously or not, guided their writings. Specifically, key essays in this Companion contextualize the GAPE within a global framework."REVIEWED BY JOHN P.
