Introduction

image of the word Scopus

 

Scopus is considered by many to be the primary competitor to the Web of Science database for citation analysis and journal ranking statistics.

The Scopus web site claims this database is the "largest abstract and citation database of peer-reviewed literature and quality web sources with smart tools to track, analyze and visualize research." It is more international in coverage than Web of Science and the Scopus interface is simple and intuitive to use.

 

View the video below for a brief introduction to Scopus.
