The dataset was used in the production of Diego Gambetta's book The Sicilian Mafia. The dataset, which is in Italian, was compiled between 1988 and 1992 by Diego Gambetta and Valeria Pizzini-Gambetta using court files and confessions of Mafiosi who turned state witness, including the autobiographical book by an anonymous Mafioso. Using a grid of topics and concepts the sources were read and strings of text containing various items - such as descriptions of episodes or individuals, of modes and justifications of behaviours, interpretations of certain actions or relations - were picked from the sources and organised in 1103 indexed 'cards' according to whether they fit one or other of the topics and concepts in the grid. These cards form the core of the dataset. By downloading the dataset and its supporting documents it is possible for the user to search and work with the data. The supporting documents include the index of key terms and concepts that were used to catalogue the dataset (dictio). Details of sources and informants are also provided within the supporting documents. Please note that the dataset and all materials associated with it are copyrighted - © Gambetta 2007.
