Google Scholar provides bibliometric tools to help you evaluate the information sources which are available through its indexing system. These bibliometric tools are measures which determine the impact of an article, an author, or a journal. Additionally, you can use metrics to locate research articles, seminal research articles, emerging topics, and find reputable journals to publish your work.
