Web of Knowledge will undergo an upgrade beginning on Sunday January 12, 2014 at 1400 GMT and ending by Monday, January 13, 2014 at 0200 GMT. Web of Knowledge may be intermittently unavailable during that period. We apologize for any inconvenience this may cause.
The result of the upgrade will be a more intuitive search experience, and the site will be renamed Web of Science. See http://wokinfo.com/nextgenwebofscience for futher details.
