Review: Muslims in Ireland: Past and Present, Oliver Scharbrodt, Tuula Sakaranaho, Adil Hussain Khan, Yafa Shanneik & Vivian Ibrahim, 2015, Edinburgh: Edinburgh University Press, 272 pp., £70.00 (hb), ISBN 978–0–7486–9688–8 (hb), ISBN 978–0–7486–9689–5 (eb) Muslims in Ireland is a landmark study of its topic. With the Republic of Ireland’s transition from a country of emigration to one of immigration from the mid-1990s onwards, it is also one of the first scholarly book-length studies of any new religion in Ireland. Such studies face particular challenges, including the need to establish baseline facts, the responsibilities arising from the fact that they are likely to remain the main point of reference for years, and the multiple publics interested in such works, leading to choices about what kind of book to write. Based on two substantial funded research projects, Muslims in Ireland is a co-written book which situates Ireland within international research in the field and sets a high standard for future research.
