Thomson Scientific has recently upgraded Web of Knowledge. The service now benefits from a newly designed interface and from greatly enhanced features, namely a more intuitive tabular format and a fully mapped all-database search.
For more details on the service upgrade, see http://wok.mimas.ac.uk/support/documentation/.
UCL Library Services provides full access to Web of Knowledge and its products. Each component can be searched from the main Web of Knowledge interface, or can be accessed individually from the list of UCL Library Services online databases.
