Search Tips
When you search, are you getting too many results? Are you not finding sources that meet your needs? Here are tips to improve your searching:
- Frame your topic. A quick way to get better results is to add the BIG subject, which usually happens to be the class you need the research for. If you’re looking for articles on the Industrial Revolution, add a key word like history, economics, or science.
- Add related terms and synonyms. Try adding key words in your search. For example, related terms like factory workers, inventions, or machines would help surface more specific sources when included with the term Industrial Revolution.
- Advance your search with filters. Use the Advanced Search options to help narrow your search. For example, narrow the publication DATE, choose FULL TEXT or PEER REVIEWED.
- Looking for something very specific? If you’re looking for a specific name or term, put it in quotation marks. Searching for “Industrial Revolution” or “cotton gin” will only bring up sources that include that exact phrase.
- Check your spelling. A spelling error can complicate your search!
