In choosing a title for this paper, we have consciously copied the name of the series of biannual conferences, started at Lancaster in 1994, which aim to bring together those who have an interest in the application of corpora to the teaching of language and linguistics. Already, those conferences have set in train a series of publications – conference proceedings (Wilson and McEnery, 1994; Botley, Glass, McEnery and Wilson, 1996), a general selection of papers (Wichmann, Knowles, McEnery and Fligelstone, 1997) and a collection of papers related to multilingual copora (Botley, McEnery and Wilson, 1997). The aim of this paper is to summarize the progress to date in the field of teaching and language corpora, both as a general introduction and as a gateway to the more comprehensive literature which is developing. As such, this paper owes a considerable debt to all of the participants at the past two conferences.
