IMISCOE is a European Commission-funded Network of Excellence of more than 350 scientists from various research institutes that specialise in migration and integration issues in Europe. These researchers, who come from all branches of the economic and social sciences, the humanities and law, implement an integrated, multidisciplinary and internationally comparative research program that focuses on Europe's migration and integration challenges.Within the program, existing research is integrated and new research lines are developed that involve issues crucial to European-level policy-making and provide a theory-based design to implement new research.The publication program of IMISCOE is based on five distinct publication profiles, designed to make its research and results available to scientists, policymakers and the public at large. High-quality manuscripts written by IMISCOE members, or in cooperation with IMISCOE members, are published in these five series. An Editorial Committee coordinates the review process of the manuscripts.
