Thomson maintains a list of ISO abbreviated name of journal via ISI Web of knowledge. It will be nice to share this list for the Endnote user.
I maintain such a list available for Endnote users:
http://www.ese.u-psud.fr/epc/conservation/SJI/Endnote_Journals.zip
but it will be more logical that Thomson itself manages and diffuses such a list.
And again, thanks for your great product !
