  5. Two BIG issues • How to search effectively & efficiently • Where to search

  6. How to search • Do a “reference interview” with yourself: • What are you looking for? Be as specific as possible. • What are some synonyms? • What do you plan to do with the information? • How current does the information need to be? • Where should you start looking?
