Library research

• What do I want to know?• Define an information need and develop a strategy

• Where do I find it?• Know where to look

• How do I know if it’s right for me?• Evaluate information before you use it

Define an information need

• Review your assignment• How many sources? What type(s)? What is the

audience? What is the intended purpose?

• Brainstorm for ideas• Talk to friends; browse web; read newspaper

• Identify main topic and related concepts• Use a thesaurus; break down by subtopic

• Put it all together• Develop a search strategy

Search strategy• Use “ “ or ( ) to keep words together & in order, i.e.,

“senior citizens” or (senior citizens)• Connect with Boolean operators

AND = narrow

OR = expand

NOT = exclude

• AND is automatically used by Google and other search engines to combine terms.

• Sometimes a program will use a + or – to substitute for AND or NOT

Know where to look• Looking for books?

• Use books for comprehensive information, often with an historical perspective

• Find books in the library catalog

• Looking for articles?• Articles are shorter and more current than books. Use when you

need in-depth but narrowly focused information• Find articles in an article database

• Looking for internet resources?• Internet resources are the most current sources for information.

Use the internet when you are looking for current information on a broad variety of topics

• Find internet resources online, but not just anywhere…

How to find: Internet Resources• Search engines not all created equal!• Subject directories organized links to resources

• Online reference Reference sources (dictionaries, encyclopedias, etc.)

• Online periodicals Some are free• Web portal may be general or subject-specific• Professional & Trade organizations websites provide industry news, directories, etc.

Is contact information provided?Who published the work? Who sponsored the work?
