This volume contains a selection of papers presented at the 11th International Conference on the History of the Language Sciences (Potsdam 2008) which are especially representative of the concerns of the conference and its thematic range. The reflection about language and the individual languages has characterized cultures since ancient times and has brought forth different traditions of the language sciences. The contributions cover the period from antiquity to contemporary history. In addition to terminological and social history approaches, they also include research results based on corpora or which reconstruct theoretical approaches. More than other scholars, linguists are turning to the history of their science for answers to current questions. This underscores the value of the history of language sciences for understanding the present state of linguistics and its development. Interdisciplinarity necessary for the research of many issues and manifestations of language makes historical reflections on the disciplines indispensable.
