Is Google Scholar better than Scopus?
Non-journal coverage – Google Scholar has more unique types of materials (PDF files, Word docs, technical reports, theses and dissertations, etc.). Web of Science and Scopus both have “some” proceedings and books but they are mainly covering journal articles. SCOPUS focuses on independent journals in the research field of Science, Technology, Medicine, and Social Sciences, however, SCIE indexing focuses on technical and scientific publications including natural and social sciences.
