Scopus is a large database that provides abstracts and citations for tens of thousands of academic journals as well as quality web sources. Its coverage is multidisciplinary, but is strongest in the fields of science and technology. You can access citations provided by this database either by searching Discover@Bolton or going to resource directly via the A to Z list of databases. There is also a link on each Subject Guide. 

Scopus is a really important research database, and may be particularly helpful when conducting a literature review.
