This paper presents a project of digital editions and research corpora of francophone diaries written by two Russian aristocrats, Alexandre Chicherine (1793-1813) and Olga Orlova-Davydova (1814-1876). The original French texts of these diaries have never been published in spite of their considerable value for research in linguistics, literature, social history and history of the arts. Alexandre Chicherin's diary contains a great number of the author's drawings that are closely related to the text of the diary entries. Olga Orlova-Davydova's diary contains interesting details on the everyday life of the Russian aristocracy and on some historical events and well-known figures. Both diaries provide rich data on the interaction of the Russian and French languages and cultures. The workflow of the project consists of a primary transcription with Microsoft Word using styles and some special characters (micro-syntax). This transcription is automatically converted to TEI XML and then imported into the TXM corpus analysis and publication platform (http://textometrie. org). Prototype corpora of both diaries are available on the TXM demo portal (http://portal.textometrie.org/demo/?command=page&path=/JournauxFrancophones).
