The Top List of Academic Search Engines
Academic search engines have become the number one resource to turn to in order to find research papers and other scholarly sources. While classic academic databases like Web of Science and Scopus are locked behind paywalls, Google Scholar and others can be accessed free of charge. In order to help you get your research done quickly, I have provided a link to Paperile which provides a list of top academic search engines.
I have added another useful search tool, Research Gate. ResearchGate is a professional network for scientists and researchers. Over 15 million members from all over the world use it to share, discover, and discuss research.
