Xavier Vinader i Sánchez (Sabadell, 1947) studied in the Barcelona School of Journalism and worked in the Diari de Sabadell and in Radio Juventud in Sabadell, as well as in the journals Can Oriach and TS. He was a correspondent for La Vanguardia, Europa Press, El Correo Catalán, Tele/eXprés and Mundo Diario. He has been an editor for Gaceta Universitaria, Mundo, Por Favor, Arreu, Primera Plana, Interviú... At the end of 1979 he published in Interviu three articles about dirty war in the Basque Coutry which involved that National Court started legal proceedings against him. He was sentenced to seven years prison. He was forced to exile, where he received the support of some organizations and international press. He came back voluntarily and was taken to Carabanchel; on the 21 of March 1984 the Government reprieved him. His course and some of his articles have deserved national and international awards. Dirty war against ETA has a special prominence in Vinader’s batch. We also find documents about the action of intelligence services and security forces on a worldwide scale. Organized crime, with a leading role of Italian, Japanese and Chinese organizations, takes up an important section. The research about desctructive sects and their way to attract followers has a considerable number of documents, as well as international prostitution networks, arms trade and mercenary organization. Nazism in its crucial moments and its attempts to spread once war was over, together with the content of the batch named Xavier Vinader i Sánchez, form a valuable archive for historians and journalists.
