'In her engrossing account of Northern Irish emigration since 1921, Leaving the North: Migration and Memory, Northern Ireland 1921–2011, Professor Johanne Devlin Trew combines a mastery of the quantitative and the qualitative approaches to her subject as she endeavors to put "migration back into history". Trew addresses a gap in the Irish migration historiography that has allowed the specific experience of Northern Irish migrants within the overall Irish migration story to fall between the cracks. ... One of the unique features of this book is that the emigrant interviews are conducted both in Northern Ireland and abroad, showing a more complete picture of the subject. ... this book is a worthy read, filling in a historiographical gap for experts while offering some thoughtful insights into the psyche of emigrants for the broader public.'Peter Moloney, Journal of World History
