Originating in a panel presentation at the eighth Accounting History International Conference, this study offers a reflection on the issues, opportunities and obstacles which may arise when accounting historians engage with other accounting scholars and scholars outside of accounting. Supporting the view that accounting scholars need and should make an effort to engage with other scholars inside and outside accounting, various aspects are considered as enhancing the interdisciplinarity of accounting history research. Then issues such as researchers and the community, research problems, theories, methods and data are addressed. The opportunities arising from interdisciplinary interactions with a wide range of scholars are then developed. Finally, the potential obstacles are addressed. This obstacles can be overcome by the development of robust communication and the invention of a new genre of discourse and research focus and by working with those outside our discipline and embracing the challenge of the new and the different.
