Comparison of PubMed, Scopus, Web of Science, and Google Scholar: strengths and weaknesses

Comparison of PubMed, Scopus, Web of Science, and Google Scholar: strengths and weaknesses

The evolution of the electronic age has led to the development of numerous medical databases on the World Wide Web, offering search facilities on a particular subject and the ability to perform citation analysis. We compared the content coverage and practical utility of PubMed, Scopus, Web of Science, and Google Scholar. The official Web pages of the databases were used to extract information on the range of journals covered, search facilities and restrictions, and update frequency. We used the example of a keyword search to evaluate the usefulness of these databases in biomedical information retrieval and a specific published article to evaluate their utility in performing citation analysis. All databases were practical in use and offered numerous search facilities. PubMed and Google Scholar are accessed for free. The keyword search with PubMed offers optimal update frequency and includes online early articles; other databases can rate articles by number of citations, as an index of importance. For citation analysis, Scopus offers about 20% more coverage than Web of Science, whereas Google Scholar offers results of inconsistent accuracy. PubMed remains an optimal tool in biomedical electronic research. Scopus covers a wider journal range, of help both in keyword searching and citation analysis, but it is currently limited to recent articles (published after 1995) compared with Web of Science. Google Scholar, as for the Web in general, can help in the retrieval of even the most obscure information but its use is marred by inadequate, less often updated, citation information.—Falagas, M. E., Pitsouni, E I., Malietzis, G. A., and Pappas, G. Comparison of Pub Med, Scopus, Web of Science, and Google Scholar: strengths and weaknesses.

    Thursday, 24th July 2014

    Information assets are in the hands of the right people to safeguard them but the wrong people to manage their exploitation concludes an influential new study. As reports continue to emerge of apparent corporate paralysis in the face of cyber security threats, Tim Buckley Owen wonders whether the emphasis hasn't swung too far in that direction, and sees opportunities for information professionals in helping to strike a balance between security in the cloud and effective data analysis for competitive advantage.

  • Click to view the article Effective Collaboration Isn't Always About the Tools
    Thursday, 24th July 2014

    When companies begin to take their first tentative steps with collaboration a first thought is often - what tool shall we use to facilitate collaboration within our organisation? James Mullan argues that the first step should be to think about what problems the collaboration tools are going to solve and what your ultimate goal is so that you can develop a plan and a strategy for the implementation of these types of tools.
