A library database is a collection of pre-paid articles, ebooks, reports, statistics, images, videos, etc. that you can search by title, author, subject, keyword, and more. You can easily limit your results to a specific source (like articles), full-text, and scholarly sources.
Google Scholar offers many scholarly open-access articles, which are freely available on the web. However, these are mixed between scholarly fee-based articles, which are available for purchase, and with non-scholarly articles.
