The purpose of this paper is to review and critique the field of Intellectual Capital Accounting Research (ICAR). The literature indicates that an organisational and business revolution is in progress concerning the need to understand the value of knowledge resources and how to manage them. The paper explores the field of ICAR by examining a decade of published research since Petty and Guthrie's (2000) seminal paper on ICA, "Intellectual capital literature review: Measurement, reporting and management" as published in the Journal of Intellectual Capital.The paper has four specific contributions. The first contribution is to identify the field of scholarship associated with ICAR. The second is to provide a comprehensive picture of what has happened in the field of ICAR over the past decade. Third, it provides evidence as to how and why the field of ICAR is changing. Fourth, it highlights areas for future research and policy developments. From these four contributions our definition of Intellectual Capital Accounting (ICA) emerges. That is, ICA is an accounting, reporting and management technology of relevance to organisations to understand and manage knowledge resources. It can account and report on the size and development of knowledge resources such as employee competencies, customer relations, financial relationships and communication and information technologies. Additionally, the analysis highlights several interesting patterns and worrying trends in the field of ICAR.
