Twenty years of interviews are brought together in this book. The topic they deal with: the craft of history. Those who talk about him: historians. Historians question their profession. They have stopped waiting for answers from a place outside their own place. Furthermore, they reflect on their discipline based on the same procedures they use in their research. The interviews that will be read in this volume, as they were done, became dialogues. From an exclusive function of questioning, we moved on to the task of exposing the interviewer's own point of view. Share questions and criticisms about your craft. The interview is a particular genre, since it is translated into different communication media. It begins in orality and ends in writing. This transition from one form to another is only achieved thanks to the fact that the communication was recorded. It is necessary to highlight that from the oral to the written form there is a profound transformation. To carry out this transformation, editing work is needed. This edition brings us back to the question of who speaks in the interview; even if the greatest care is taken to respect what the interviewee said. It will always be an enigma of the interviewee and the interviewer in the product. As a historian, the only thing that can be said is that we must stop being naive when reading them.
