A project was conceived to open, at no charge to the public, all historic and official documents drafted in preparation of the text, not only of the OECD Model Convention of 1963, but also of the older convention drafted under the League of Nations. The official texts are made available in the two languages in which they have been drafted: English and French. The data base contains several search functions based (1) on language, (2) on chronological order, (3) on the reference of documents and (4) the committee or department dealing with the document and (5) last but not least a full text research function in French and English.
