Unfortunately the first work of our software expert is only available to a very restricted readership – the members of the Lasker Society. Much to our regret, as you cannot imagine a better survey on the life and the work of Jean Dufresne.
PS: An enlarged second edition was published in 2006 (small number of copies as well), but a third edition is already anounced for 2007 ...
