"This collection encompasses a wide range of topics centered on the Río de la Plata region. ... this edited volume is a fitting tribute to Susan Socolow, mentor of the three editors and other contributors. Socolow created not only well-regarded scholarship (which inspired several of the chapters in this collection) but also connections that brought together historians from South America and the United States and bridged multiple subfields." (Amílcar E. Challú, Hispanic American Historical Review, Vol. 105 (1), February, 2025)
