The internet is a vast sea of information with no organization.
Library databases offer options to quickly limit or expand your search to find the articles you need.
A search engine (like Google) often returns an overwhelming number of results with no quick way to narrow them down or ensure they relate to your topic.
In short, you should use library databases to quickly find relevant scholarly information you can use in research papers or other course projects. We also have several library databases that include music, videos, and art!
