This book focuses on aspects of variation and change in language use in spoken and written discourse on the basis of corpus analyses, providing new descriptive insights, and new methods of utilising small specialized corpora for the description of language variation and change. The sixteen contributions included in this volume represent a variety of diverse views and approaches, but all share the common goal of throwing light on a crucial dimension of discourse: the dialogic interactivity between the spoken and written. Their foci range from papers addressing general issues related to corpus analysis of spoken dialogue to papers focusing on specific cases employing a variety of analytical tools, including qualitative and quantitative analysis of small and large corpora.
