The new interface to the Web of Science, an interdisciplinary (humanities, science,social science) database indexing about 9,000 journals will be available in the next few weeks on the UT Libraries database menu.
The cited reference search and the citation alerts are two of its most useful features.

The new Web of Knowledge/Web of Science (a.k.a. Science Citation Index) interface BETA version is available until August 19th.

You can jump right in and try the beta version at the link above. Or, while you wait for the more finished new interface you can get ready for it by signing up for training, taking a tour, etc. on the ISI announcement page.
