It seems that students love Google Scholar. Let me relate an incident to you about a chemical engineering student who was referred to me by his professor. I showed the student how to do his search on a topic related to nanotechnology in Scifinder and Scopus. After this was completed he told me he had already done the search in Google Scholar. He said that he attended my seminar last fall when I discussed the subscription-based databases. I looked into my records and saw that just after the seminar he opened a Scifinder account, but apparently never used it.
Go figure!
