IZA (Germany) - Database of migration articles
Migration literature database now featuring more than 10,000 entries. IZA focuses on economics and labor issues, so many of the articles will be on that, but they also have papers on naturalization, family patterns, and indicators of other forms of integration. The studies will be largely statistical, done by economists. Since many economic papers get widely circulated as working papers before they actually get published, this is a nice database to see what sort of working papers are out there.
