Nutrition 499 (Kim): Finding Articles

This research guide will point you toward print/online research resources and strategies available to you for your Research Paper Assignment in Nutrition 499. Use this guide throughout the research process to help you have the best support for your thesi

Ask yourself - Where should I be looking? What type of resource will meet my information need?

If journal articles are not the place you are likely to find the information you are seeking, try looking in books (Library Catalog and Google Books)


Example of a Boolean Search in PubMed

Boolean Operators

Boolean operators allow you to combine your keywords into search query that the databases understand. The words AND, OR are the most commonly used Boolean operators. The third is NOT, which is difficult to use because it can exclude useful results. 

AND combines your search terms and looks for them together in search result. Example: A search for Hip Hop Music AND Rap Music will retrieve records that have both keywords; Hip Hop Music and Rap Music.

OR separates your search terms, finding records that contain either keyword. Example: A search for Hip Hop Music OR Rap Music will retrieve records that contain just one of the search terms as well as records with both of the search terms.

NOT finds records that only have the first keyword, excluding the second keyword. Example:  A search for Rap NOT Country will find only records containing the Rap but not the second keyword. However if there was an article title: Why Rap Music Tells a Better Story Than Country Music, the database will ignore the article even though it is useful because of the use of the Boolean Operator NOT. I do NOT recommend use of this Boolean Operator, it can be too exclusive and hurt your research.


Additional Examples

Question: I want to know more about music's influence on Urban Culture?

Your search should be constructed as an using Music AND Urban Culture. Your results will include records where both terms appear.

You can add an additional term to your search such as Los Angeles. Your search will be narrowed down to only have results that have all three words  Music AND Urban Culture AND Los Angeles.


Question: I need to find information on Freeways?

Think of synonyms for the word, Freeways OR Highways will help you retrieve more results.


Question: I am look for information on Hybrid Cars?

By NESTING you can use both AND and OR: Hybrid  AND (Cars OR vehicles)
