The collection Europe of Migrations: Policies, Legal Issues and Experiences brings together scholars from law, sociology, history, and political science with the aim of taking the stock of these topics. The volume focuses particularly on three aspects: firstly, how the European Union is facing to the emergency of great fluxes of migrants, while its policies and rules are explicitly questioned or opposed by some Member States; secondly, which are the major legal issues at stake regarding the integration of migrants in the European countries; thirdly, how welcoming policies are dealt with national and local bodies and which matters involving ethnic diversity and new migrant communities may arise from specific experiences.
