From: "Calderone, Laura" <[log in to unmask]> Date: Wed, 26 Sep 2012 15:18:25 +0000 One factor that I haven't seen mentioned is that Google Scholar searches full-text rather than metadata only. This is a very significant difference. I always use commercial A&I databases as well as Google Scholar for this reason. For more esoteric topics I have found things on Google Scholar that were not returned in a search of the A&I databases.
