While the field of learner corpus research has made a great deal of progress since its advent some thirty years ago, there are still areas that remain to be explored. In this chapter, two such areas, related to temporal evolution, are demarcated. The first one is diachronic learner corpus research, which considers the possible evolution of learner language through time, as a result of changes in the typical acquisitional context or in the norms that learners depend on, for example. The second one is process learner corpus research, which uses screencasting and keyboard logging to examine the evolution of learner texts during the writing process and to gain insights into learners’ competence on that basis. These areas require new types of learner corpora, some of which are introduced and tested through small case studies. Preliminary results confirm the relevance of diachronic learner corpus research and process learner corpus research and thus underline the dynamic nature of learner language, which changes and evolves in many different ways and at many different levels.
