This volume explores potential paths in historical sociolinguistics focusing 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 with 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 historical-sociolinguistic field and presents fruits and challenges of interdisciplinary collaboration.
