Video: What are Library Databases and Why do you Need Them?

Types of Articles

There are many different types of articles. The chart below can help you figure out which type(s) you're looking for or identify an article you've already found:

They are written by experts in the field (the people with letters after their name!) and their purpose is to advance the ongoing body of work within the discipline. These articles might present original research data and findings, or take a position on a key question within the field. They can be difficult to read, because their intended audience is other experts and academics, but they are at the top of the line when it comes to authoritative information.

New to scholarly science journals?  Reading scientific literature is different than reading a novel or a news article. They are not as well written and they make you work harder to understand. Here are some tips on how to read a scientific article:

Advanced Google Seatching

One of the best features of Google's advanced search is the ability to limit your search to the areas of the web where the information is most reliable, such as education sites or government sites. The shortcut for this is to add site:edu or site:gov to your regular Google search.

For example, if you conduct an ordinary Google search for nutritional supplements, most of your top results will be commercial (.com) sites trying to sell you vitamins. If you search for nutritional supplements site:gov , the top results (except for the sponsored ads) will be sites such as the National Institute of Health and the Food and Drug Administration, which are authoritative, unbiased sources that are not trying to sell you anything. If you search for nutritional supplements site:edu, your top results will be from universities providing research on nutritional supplements.
