Searching with Keywords

Boolean Operators

Boolean operators are words you can use to combine search terms. The basic operators available to use in academic research databases are AND, OR, and NOT. To get more results, use OR with a related word. To get fewer results, use NOT with a related word that appears in your results but is not relevant to your research question.

If you search peanuts, you will get results that use the word in any way:


NARROWER SEARCH: If you search peanut AND butter (or just peanut butter), you will only get results that have both words:


BROADER SEARCH: If you search peanut OR butter, you will get results that have one or the other or both words:


NARROWER SEARCH: If you search peanut NOT butter, you will get results that have the word peanut but not the word butter:

Scholarly vs. Popular

Do you want to know how to determine if an article is scholarly or popular? see this tutorial by University of North Carolina at Chapel Hill Libraries.

Popular, Professional, & Scholarly Sources

Periodical is a term used to describe any publication that is published multiple times (periodically). Periodicals include materials such as popular magazines, scholarly journals, professional journals and newsletters, and newspapers.

It is important to understand the difference between a popular and a scholarly periodical. When you are doing research, most of your sources should be scholarly or professional.

Often popular periodicals are called magazines and scholarly periodicals are called journals. Many times it will be acceptable to use some popular material, but research papers should not be based solely on popular literature.
