Abstract:

The evolution of the electronic age has led to the development of numerous bibliographic databases on the World Wide Web, offering search facilities on a particular subject and the ability to perform citation analysis. The most popular ones are Google scholar, PubMed and Web of Science.

Numerous articles have examined there search ability, but few have asked whether there accuracy is enough for scholars. This study will be based on the systematic literature reviews providing an insight on the accuracy of these databases’ citation counts, Citations, Metrics, Research data, metadata and search processes, their strength and weakness. The aim of this study is a systematic review of a comparison of these three frequently used databases based on the accuracy of their information.

This study not only helps academicians, students, instructors to gain useful insights on the accuracy of these databases as research tools but also provides evidence on how to maintain accuracy measures when using these databases.
