Global sourcing has been one of major trends of last decades and has gained considerable momentum in the academic debate. After more than thirty years of research on this topic, the aim of this paper is to evaluate the evolution of the field and understand its intellectual structure. Rather than conducting a traditional systematic literature review, we employed the bibliometric citation and co-citation techniques to achieve the aforementioned aim. This allowed us to identify the major publications in the field and map the main topics/methods/theories and the underlying general relationships between them.
