Pros |
Provides a more comprehensive picture of scholarly impact as it indexes non-traditional sources not covered by WOS and Scopus Includes peer-reviewed papers, theses, books, abstracts, and articles from academic publishers, professional societies, preprint repositories, universities, and other scholarly organizations Better coverage of newer materials than both WOS and Scopus International and multi-lingual coverage |
Deeper back-files especially for Science Journals While controversial, its journal citation reports, impact factors, and h-index are most widely used Offers citation mapping for visual presentation Does not include technical reports, theses and dissertations, conference proceedings, and books |
Cons |
Limited search features Inflated citation counts due to inclusion of non-scholarly sources such as promotional pages, table of contents pages, course readings lists etc. Weeding irrelevant hits is time consuming Difficult to export citations No way to determine what sources, and time spans are covered. Limited to what is available on the Web |
Can lead to low citation counts due to errors in citations provided by authors, and different citation styles used by journals leading to poor indexing More difficult to use Coverage in the sciences is more through then in the arts, humanities, and social sciences. |
