Over the last three decades, historical sociolinguistics has developed into a mature and challenging field of study that focuses on language users and language use in the past. The social motivation of linguistic variation and change continues at the forefront of the historical sociolinguistic enquiry, but current research does not stop there. It extends from social and regional variation in language use to its various communicative contexts, registers and genres, and includes issues in language attitudes, policies and ideologies. One of the main stimuli for the field comes from new digitized resources and large text corpora, which enable the study of a much wider social coverage than before. Historical sociolinguists use variationist and dialectological research tools and techniques, perform pragmatic and social network analyses, and adopt innovative approaches from other disciplines. The series publishes monographs and thematic volumes, in English, on different languages and topics that contribute to our understanding of the relations between the individual, language and society in the past.
