This article claims to be both a review and an agenda-setting piece. It is argued that e-government research suffers from definitional vagueness of the e-government concept, oversimplification of the e-government development processes within complex political and institutional environments, and various methodological limitations. In order to address these issues, the article reviews the limitations in the e-government literature, and it suggests ways forward. To do so, the study critically analyzes the development and various definitions of the e-government concept. After discussing the limitations of the concept, methodological and conceptual remedies such as (i) better examining and explaining the processes of - and participation patterns in - e-govemment projects within complex political environments, (ii) addressing the problem of under-specification in the e-government literature by the production of more grounded, empirical studies that would create new theoretical arguments and provide new concepts and categories so as to enhance our understanding of e-government policy processes and actors, and (iii) tying the subject of e-government strongly to mainstream public administration research are suggested in the final part of the analysis.
