"Third language acquisition and trilingualism have recently come more and more into the focus of applied linguistics. While the research trends of product-orientated bilingualism and process-orientated second language acquisition have tended to follow largely different tracks, third language acquisition and trilingualism are in much close contact. With its comprehensive multidimensional coverage of English as a third language in Europe the present volume provides a welcome contribution to a rapidly expanding field of research" -Hakan Ringbom, Abo Akademi University
