The aim of the paper is to provide an overview of the current stock-flow consistent (SFC) literature. Indeed, we feel the SFC approach has recently led to a blossoming literature, requiring a new summary after the work of Dos Santos (2006) and, above all, after the publication of the main reference work on the methodology, Godley and Lavoie's Stock-flow Consistent Approach (2007). The paper is developed along the following lines. First, a brief historical analysis investigates the roots of this class of models that can be traced as far back as 1949 and the work of Copeland.
