Google Scholar - Google Scholar limits search requests to its library of scholarly papers and journals. The results show the standard title and description, but it also displays the date of the paper, the source, the author, and the number of times each paper has been cited by other scholarly sources. If you need serious data and vetted knowledge, this is an excellent resource. Quoting these sources in your proposals can add scholarly weight to back up the strategy or direction you are recommending to your client.   next >
