Henri Goursau is featured in the Guinness Book of Records for his "International Travellers’ Dictionary in 16 Languages" published on 21 February 1997 at Saint-Orens de Gameville (France). His dictionary holds the absolute world record for containing the highest number of languages!

The absolute world record for “The International Dictionary containing the most number of languages” has been included in the Guinness Book of Records and the Guinness certificate was awarded to him on April 4, 1997 by the ratifying committee. Having written and published more than twenty dictionaries in 30 years, Henri Goursau already has an impressive list of honours: in 1984 he received a certificate from the Aero-Club of France for the quality of his dictionary of aeronautics and space technology. In 1985, he was awarded the aeronautic medal at the suggestion of the Minister of Transport. In 1988, he was awarded first prize among 300 candidates at the Midi-Pyrénées Regional Videotex competition for his proposal for the creation of a “European Centre for Telematics Terminology”.
