I must recognize half a lie. ISI has a strategy of conquest of the french market about the Web of Science. They offer 2 months free and illimited access (starting a few days ago). For supporting this strategy, ISI has designed the 301 french laureates according to citation criteria : http://www.isinet.com/emea/tourdefrance/laureates.htm In this list, the laureates were selected for 22 broad disciplines, and it is taken account of the fact that some disciplines may lead to few citations. They win a diploma ;;-), if they come to receive it at a demonstration of the WoS ;;;-)). All that to explain why I have access to the WoS. Of course, crystallography is not a discipline, and powder diffraction even less. So I decided to design myself the powder diffraction laureates ;;;;-))). I may send them a diploma if they wish ;;;;;;-)))). The lie is there : between 1975 and 1990, the search was made by using the words "powder" AND "diffraction". Before that, I performed also a full more restrictive search with 4 words : "powder" AND "diffraction" AND 'structure" AND "determination". Then, when I wanted to complete the 1991-2001 period with only "powder" AND "diffraction", the WoS replied that the "time allocated for this server was over"... Ooooops. Well, you see, 2 months free trial with something unsaid: a limitation somewhere in the system... But I promise : if I recover access, I will finish the job ;-). Or somebody could do it and send me the result ? Best regards, Armel PS- Maybe your country is the next ISI target. Be prepared to receive a diploma.
