There has been a large quantity of research that has been carried out on interorganizational systems in recent years. Because research in this area has been carried out for a long time, it is becoming increasingly difficult to find new aspects of it to explore. The aim of this study is to identify the published literature on IOS from 2006 to 2015, review them, and apply a suitable framework to categorize them based on the aspect of the topic they explore. The categorization framework employed for the study consists of four broad categories: IOS infrastructure, IOS assimilation, IOS dynamics, and IOS impacts. We further present a comprehensive reference of the reviewed literature. We hope to contribute in guiding future researchers of IOS by showcasing aspects of the topic that has been researched, and help them discover new avenues of IOS to explore.
