The Transnational Communities Programme was a research program directed by Professor Steven Vertovec of the Institute of Social and Cultural Anthropology (ISCA) at the University of Oxford, dealing with various aspects of transnational communities. Other institutions including the London School of Economics and Cambridge University collaborated on the project. The program comprised 19 projects, with research concentrated in four main areas: new approaches to migration (horizontal migration, situational comparison of different diasporas, refugees and political asylum seekers); economics (global economic links, transnational corporations); politics (global political links, gender, society and power); as well as culture and society (social classes and institutions, cultural reproduction and consumption, supranational religious communities).

The website contains many interesting articles (authors include Zygmunt Bauman), an extensive bibliography divided by country, information about projects carried out within the program, and online journals such as The International Library of Studies on Migration.
