Google Scholar is a web search engine that specifically searches scholarly literature and academic resources. Google Scholar can be a useful resource but keep in mind that it is a search engine, not a library database. Google Scholar may search through academic sources but that does not mean that everything found on it is a fully reliable source. It is up to the researcher to determine if the source is reliable. The selection that Google Scholar makes for you is not transparent and searches are not always reproducible. It ranks the search results and shows only the first 1,000 results of any search, based on algorithms that change frequently.
