This volume explores potential paths in historical sociolinguistics, with a particular focus on the inter-related areas of methodological innovations, hitherto un- or under-explored textual resources, and theoretical advancements and challenges. The individual chapters cover Dutch, Finnish and different varieties of English and are based on data spanning from the fifteenth century to the present day. Paying tribute to Terttu Nevalainen's pioneering work, the book highlights the wide range and complexity of the field of historical sociolinguistics and presents achievements and challenges of interdisciplinary collaboration. The book is of interest to a wide readership, ranging from scholars of historical linguistics, sociolinguistics, corpus linguistics and digital humanities to (advanced) graduate and postgraduate students in courses on language variation and change.
