Obviously Belk Library has access to many more databases than I can list here! Which database will work best for you depends on your topic. Here are just a few that cover some aspects of Hispanic cultures.
You're probably familiar with Google Scholar, a way to search only scholarly resources in Google. But did you know it came in a Spanish-only version? Remember to enter your search terms in Spanish: for example, not "immigration United States" but "immigración Estados Unidos."
