Throughout history, linguists and literary scholars have been impelled by curiosity about particular linguistic or literary phenomena to seek to observe them in action in original texts. The fruits of each earlier enquiry in turn nourish the desire to continue to acquire knowledge, through further observation of newer linguistic facts. As time goes by, the corpus linguist operates increasingly in the awareness of what has gone before. Corpus Linguistics, thirty years on, is less an innocent sortie into corpus territory on the basis of a hunch than an informed, critical reassessment of existing.
