Because GALILEO aggregates many different types of materials (newspapers, journals, magazines, videos, photographs, statistics, etc), it's the most comprehensive way to search for academic journal articles.
However, many of its materials are not scholarly, peer-reviewed resources, so you'll need to be careful when choosing which resources to reference in your research papers.
Use quotation marks to turn words into phrases. For example, searching for either "working mothers" or "common core" will only give you search results where the two words are used together as a phrase. When you search these words without the quotation marks, your results will show one word or the other, and sometimes both together, so using quotation marks guarantees that both of your search terms will be in the articles in your results list.
In most, but not all, databases, using an asterisk at the end of a word will search for all variations of that word. For example, searching for "educational strategy*" will give you search results containing either "educational strategies" or "educational strategy," as well as other variations of the phrase.
Boolean Operators give you more control over your search results. Boolean search logic lets you relate different search terms through the use of three Boolean Operators: AND, OR, NOT. You can find these operators in the Advanced Search section of GALILEO.
The word AND will limit your search results by combining two or more key terms or phrases. For example, searching for "Global Warming" AND "Climate Change" will decrease your number of search results by only giving you the results that include both phrases.
The word OR can be used to expand your search results by including terms that are used interchangeably. For example, the words Adolescent and Teenager are synonyms. Searching for Adolescent OR Teenager will increase your number of search results by giving you results that include either one term or the other--or even both terms.
The word NOT will exclude certain terms from your search. For example, searching for "Gap Year" NOT Britain will decrease your number of search results by not including results that talk about Britain.
