The library is currently running a trial of Scopus (http://www.scopus.com). Scopus is an abstract and citation database of research literature and quality web sources. It includes many tools that allow you to look at what articles are being cited, examine new trends in research literature, and the ability to create alerts to notify you when new articles are published in any research area.
If you have any feedback, please send us an email at engreference@stanford.edu.
