As a librarian I often get asked this question. Both Google and Google Scholar are good tools but sometimes they are not the best tool. There are good reasons to learn to use scholarly databases for your research, not just Google and Google Scholar.
If you only rely on Google Scholar for academic research you'll miss relevant and important research that isn't available for free online. Why is this? Well, most digital scholarly information is behind paywalls and there is a large volume of information that isn't online - both new and old - that Google Scholar can't index.
The nice thing about most of the Library's scholarly databases is that they cover both open and paywalled information as well as digital and paper resources
So, go ahead and start with Google Scholar but don't forget that there are other tools that can help! You can find these on other library guides or browse a list at the link below.
