Scholarly articles are peer-reviewed materials published in academic journals. Databases hold records of the articles from the academic journals so that you can find them. Different databases have different journals included and thus they will all have different collections of articles. The best way to find scholarly articles is to search in academic databases. Use the tips below then use the Databases tab to navigate to different science focused and general databases. 

How to Search in Databases

1. Think about what you want to know
   The first step to successfully searching is having a mindset of inquiry. Design research questions when you develop your hypothesis, design your experiment, and explain your results. 
   Example: How does salinity affect rates of photosynthesis in Arabidopsis plants? 
    
2. Gather a little background info and adjust the question as needed
   Go ahead, Google it. Or look in the library Reference section. 
    
3. Narrow the question down to the main concepts and variables
   Example: How does salinity affect rates of photosynthesis in Arabidopsis plants? 
   salinity photosynthesis Arabidopsis
   ​
4. Explore synonyms for your search terms.
   Examples: Salinity: Salt concentration, salt level. 
   Arabidopsis plant: A. thaliana
    
5. Plan a search with Boolean operators and modifiers: 

   Symbol	Example	Description
   AND	(cats) AND (dogs)	Adds search terms to the search, will limit the results to only articles that contain both terms. AND is usually implied, but can be used with parentheses and OR to make the search more precise.
   OR	(Arabidopsis OR "A. thaliana")	Expands the search, a good way to add synonyms or binomial names to search terms. This example will return any article with either the word "Arabidopsis" or A. thaliana.
   NOT	Ash NOT tree	Excludes articles that have the term. This will return results with the word "ash" but not if the results also contain the word "tree."
   *	bio*	Signifies a truncation symbol. Will yield articles with the prefix submitted and any ending, such as:  biology, biological, biome, biometrics, biography, biotic, etc.
   " "	"breast cancer"	Searches the exact phrase found in the quotes. This search will yield articles with "breast cancer," but NOT articles that only contain the word breast, or the word cancer, or contain the words separately such as cancer of the breast.

   Example: (salinity OR salt) AND (photosynthesis) AND (Arabidposis OR "A. thaliana") 
    
6. Enter your search in the library ESearch tool or a library database.
    
7. Filter and sort your results
   Try the limiters (usually on the left side of the results pages) or sort the results by most cited, or newest. 
    
8. Read titles and abstracts to get an idea of source content. 
    
9. Find the full text and read the sources.
    
10. Look up the citations in the sources you find for more potential sources. 
     
11. Repeat these steps as you focus your research topic and RE-SEARCH!
