The papers in this volume show the range and direction of current work in historical semantics and word-studies. There is a strong focus throughout on semantic change and lexical innovation, interpreted within a sociolinguistic, cultural or textual context. Many of the papers draw on the remarkable range of electronic resources now available to historical linguists, notably corpora, dictionaries, bibliographies and thesauruses, and show the effects that these have had in stimulating new lines of research or the re-interpretation of previous conclusions. Cognitive semantics, and especially prototype theory, emerges as a challenging theoretical framework for much current research. The volume contains a selection from papers presented at the 10th International Conference on English Historical Linguistics (10ICEHL). They include work on historical lexicography and an account of the workshop on electronic dictionary resources, such as the Revised Oxford English Dictionary, which formed the centrepiece of the Fourth G. L. Brook Symposium.
