This volume celebrates the contribution of Professor Colin Williams, an immensely important and influential scholar in the field of language policy for more than forty years. Eighteen chapters by former students, colleagues and collaborators address a range of topics involving different aspects of language legislation and language rights, governance, economics, territoriality, land use planning, and onomastics. Six chapters address policy issues in Professor Williams's native Wales while others focus on Canada, Catalonia, Ireland and Scotland. The volume concludes with an Afterword by Professor Williams himself. The book will be suitable for postgraduates and researchers not only in the field of language policy and planning but also sociolinguistics, geography, law and political science.
