This series offers a wide forum for work on contact linguistics, adopting an integrated approach to diachronic and synchronic manifestations of contact, ranging from social and individual aspects to structural-typological issues. Topics covered by the series include psycholinguistic and acquisition-oriented aspects of child and adult multilingualism such as bilingual language processing, second language acquisition, and bilingual first language acquisition; social, formal-structural, and conversational aspects of code switching; diachronic and typological aspects of contact-induced language change such as lexical and structural borrowing, contact languages, pidgins and creoles, convergence, and linguistic areas; as well as societal aspects of multilingualism, language management in multilingual societies, receptive multilingualism and lingua francas, language maintenance and language shift, multilingualism in computer-mediated communication, and more. The series does not have a fixed theoretical orientation and welcomes contributions from a variety of approaches.
