silent changes in WoS

[Vladimir Pislyakov]

Dear Iain,

Thank you, I tried to test it on several years and this method seems to
produce results very close to the figures obtained earlier. It means that in
October 2008 about 12% of "Articles" changed their document type to
"Proceedings Paper", unusual thing.

Kind regards,
Vladimir
