This volume hopes to act as a catalyst for some new and exciting areas of enquiry in the more "liminal" interstices of Irish Studies, Traveller Studies, Romani Studies and Diaspora and Migration Studies. These disciplines are all relatively new areas of enquiry in modern Ireland, a country whose society has witnessed very rapid and wide-ranging cultural and demographic change within the short space of a decade. The issue of multiculturalism is not one which is particularly new to Irish society as a number of contributors to this volume point out. What is new however is an increased acknowledgement of diversity and multiculturalism in Ireland and Europe as a whole. Such an acknowledgement makes increased dialogue between "mainstream" society, older minorities such as the Irish Travellers and the many newer immigrant communities such as the Roma all the more necessary. For such constructive dialogue to take place it is vital that migratory peoples and their particular expressions of postcolonial identity be voiced and valued. These identities are both complex and diverse and frequently straddle a number of countries and national identities. It is hoped that this volume will go some way towards the cultivation of such dialogue.
