The goal of this volume is to examine academic discourse (AD) from cross-linguistic and cross-cultural perspectives. The adjective Cross-cultural in the volume title is not just limited to national contexts but also includes a cross-disciplinary perspective. Twelve scientific fields are under scrutiny in the articles. One of the unique aspects of the volume is the inclusion of a variety of foreign languages (English (as a lingua franca), Spanish, French, Swedish, Russian, German, Italian, and Norwegian). Besides, in several articles dealing with oral AD, comparisons and parallels are also established with written AD. The research methodologies used in the studies are varied and they offer an overview of the diversity and richness of approaches to AD.
