  1. 1. LIBRARY INSTRUCTIONCHEM 2500Erin L. NagelSpring 2013
  2. 2. Information Literacy Outcomes Recognize an information need and formulate research questions  Develop a search strategy Identify a variety of types and sources of information  Evaluate information resources Efficiently access information relevant to the identified need  Implement and refine search strategy
  3. 3. Search termsBoolean operatorsSearch methodsDEVELOPING A SEARCH STRATEGY
  4. 4. Search strategy Identify main concepts and related terms Use “ “ or ( ) to keep words together & in order, i.e., “radiation chemistry” or (radiation chemistry) Connect with Boolean operators • AND isAND = narrow automatically used by Google and other search engines to combine terms.OR = expand • Sometimes a program will use a + or – toNOT = exclude substitute for AND or NOT
  5. 5. Search terms Use these anywhere CONCEPT 1 CONCEPT 2 CONCEPT 3 OR OR OR AND AND OR OR OR• (Concept1 OR Synonym1A) AND Concept 2• Concept 1 AND (Concept2 OR Synonym2B) AND Concept3• (Concept1 OR Synonym1A OR Synonym1B) AND Synonym3A
  6. 6. Search methods• Keyword • Everyday language • Searches everywhere in an item’s record • MORE results, but may be LESS accurate• Subject • Formal language • Specific, predetermined terms • FEWER results, but may be MORE accurate• Other fields • Search in specific fields like Title or Author • Options vary by database
