Academic databases are online collections of scholarly articles, research papers, and other academic resources. They help students, researchers, and professionals find reliable information on various topics. Popular examples include JSTOR, PubMed, and Google Scholar, which provide access to peer-reviewed journals and publications. These databases are essential for conducting thorough research, as they offer a wealth of information that is often not available through regular search engines. By using academic databases, users can ensure they are referencing credible sources, which is crucial for writing essays, theses, or any academic work that requires solid evidence and support.
