What is the difference between library databases and search engines?
Great question! Search engines crawl the entire web. Most are commercial businesses that make money from ads placed above the search results, from user clicks, and from the data they collect on users. Search engines like Google and Bing only index a fraction of the content on the web — the rest, known as the "invisible web" or "deep web," is beyond their reach. Since so many books, journals, magazines, and newspapers are now published online, a search engine can pull up material that may be useful for your coursework. However, publishers still need to make money, so the books or articles you find through a search engine may not be free.
Library databases, on the other hand, are built specifically for college-level research. They search focused collections of journals, magazines, newspapers, ebooks, and more, often organized around a particular subject area. This is content that search engines simply can't index or access.
Which should I use?
It depends on the context! Are you looking for some basic background information on a topic? Or maybe some information from a specific government or organization? Or just some general information like menus or hours for a local restaurant? Then a search engine might be right for this particular search. If you need more in-depth information, or more trustworthy information on a specific topic, library databases are the way to go.
