In this chapter, the authors introduce corpus-assisted discourse studies (CADS), a means of using the methods of corpus linguistics to facilitate discourse analysis of large volumes of textual data. The chapter uses this framework not only to demonstrate the value of CADS but also to explore the importance of repeating studies over time to test the degree to which discourse is static, or changes, through time. By extending a study of the representation of Muslims and Islam in the UK press, the chapter shows the value of exploring the dynamic nature of discourse as a way of cautioning against the idea that discourse is necessarily stable across time.
