This chapter presents an outline of some of the different types of digital datasets and tools that are currently available to help researchers in the analysis of multilingualism and its effects on the development of medieval English. A complete survey of all existing material is infeasible and will rapidly become outdated, and so the goal is instead to discuss representative examples, in order to illustrate what is currently possible with the broad range of methodologies and tools that is at our disposal. Rather than presenting a simple list, the discussion instead focuses on different stages of typical workflows and seeks to provide a realistic assessment of the potential and limits, as well as suggestions of where we might usefully go in future.
