The articles in this volume investigate everyday textual material of sociolinguistic landscapes in the early 21st century. Sociolinguistic landscapes reflect societal change, and they enable observers to map what linguistic resources are used in various contexts and to study how these resources interact and are interpreted. The articles present not only quantitative results of the presence of languages in signs but also look into how authors and designers make use of an endless pool of linguistic resources, how visible semiotic items contribute to create a sense of space, what types of mental processes are involved in the production, and how various audiences (residents, occasional passers-by, and language regulators) interpret and construct signs and sociolinguistic landscapes to form their own understanding of semiotic space.
