The book presents the results of multi-parameter corpus research on Polish and English linguistic discourses. The results show the changes which English and Polish linguistic discourses underwent between 1980 and 2010, and the extent to which English as lingua franca of modern science affects Polish L1 and English L2 linguistic discourses.

The volume provides an overview of discourse perspectives on academic genres. The authors discuss the changes which academic genres have undergone in the context of scientific communication and against the evolution of postmodern culture and society. Cultural heterogeneity of academic genres is shown to give way to their increasing hybridization.
