Scopus includes bibliometric data for the publications, or sources, which it indexes. To find and compare this data, click on the Sources tab at the top of the screen.
Bear in mind that information about a publication doesn't necessarily say anything about the individual papers in it - there is always a very wide variation in citation rates among individual items.
