Bibliometrics and Altmetrics: Measuring the Impact of Knowledge

This guide includes information on which of the databases contain citation measures that can be used to gage either an author, article or journal impact.

Introduction

Certain disciplines, journals, and document types may not be well represented in the more traditional sources for citation analysis, such as Web of Science.  In this situation, it becomes necessary to find alternative sources for locating citations to an author or published work.  This page identifies potential alternative sources grouped by their database search interface since each of the sources within a group would have a common search strategy for extracting citation information. 

Click on any option below to go to the information for that source:

Be Aware: Each of these collections has a somewhat different search mechanism, so the directions given here have been written in general terms that then must be applied to the specific search entry requirements of a given collection. 

    1. Search the full text articles, including the references, for the author last name and the article title to be cited using the advanced search option if available.
    2. If necessary, enclose the title words in quotations to force searching as a phrase.
