Whatever You Say, Say Nothing by Gilles Peress. Published by Steidl.
This huge and remarkable book, comes from Peress shooting in Northern Ireland for a period of 25 years. The book is laid out as a series of days, and within this there is a big variety of shooting methods, from panoramas to blown up contact sheets and still images from the TV. To accompany the two volumes there is also a book of Annals where all the key players and events in Northern Irish history are explained. This is the most thorough and brilliant documentary project I have ever seen.
