This selection of edited papers from the third international conference on Teaching and Language Corpora, held at Keble College Oxford in 1998, bears witness to the continued expansion of this interdisciplinary field. The use of computer corpora is no longer seen as an end in itself, but rather as an indispensable tool in language pedagogy, both by providing better grounded decisions about the topics to be taught and by facilitating the production of better teaching materials. Computer corpora also encourage a shift towards learner-centred exploratory teaching practice, which are shown to be effective in a wide variety of contexts.
