What is Google Scholar?
Google Scholar consists primarily of scholarly articles including journal papers, conference papers, technical reports, theses, pre-prints, post-prints, abstracts and court opinions. Google Scholar automatically includes scholarly works from Google Book Search.
Google Scholar's strength is the broad scope of content for both types of publications and disciplines. There is also a better international and multi-lingual coverage.
