“…Translations of their publications, or primary publications in English, have historically been scarce, however they are increasingly appearing (Murail et al, 2004;Nilsson Stutz, 2003a, 2003bPautreau et al, 2004;Peressinotto et al, 2004;Roksandic et al, 2006;Valentin et al, 2000;Zeitoun et al, 2004).
