Salikoko S. Mufwene is the Edward Carson Waller Distinguished Service Professor of Linguistics at the University of Chicago. His current research is on the phylogenetic emergence and speciation of languages, and on language vitality. His books include The Ecology of Language Evolution (Cambridge, 2001), Iberian Imperialism and Language Evolution in Latin America (2014), and Bridging Linguistics and Economics (Cambridge, 2020). He is the founding editor of Cambridge Approaches to Language Contact. Anna María Escobar is Professor Emerita at the University of Illinois at Urbana-Champaign. Through the study of grammatical change, her work focuses on the emergence of contact-induced linguistic outcomes and minoritized Spanish varieties. Her long-term project focuses on the making of Andean Spanish, with colonial and post-colonial corpora.

'In this two-volume Cambridge handbook, Mufwene and Escobar have assembled four dozen novel studies on linguistic change, as induced or conditioned by migration, language contact, multilingualism and population structure. This hefty new reference work provides an important resource on language change in the living context of human societies.' George van Driem, Chair of Historical Linguistics, University of Bern
