General Search Tips
Many (if not most) of the historical primary sources we have access to are from a western/white/colonial perspective.
When searching for primary sources keep in mind that the country names, names for groups of people, etc. have changed over the years. You will often get better results if you try searches using both modern and historical terms.
If you are interested in a particular country, try searches for the country name as well as the region, i.e. Ghana OR West Africa.
Pay attention to the publication dates for secondary sources - scholarly methodologies and perspectives can change
How you enter your words into the search box makes a difference in the results you get:
Use AND to connect different concepts and narrow your search
Example: (food AND politics)
Use OR to connect synonyms and similar concepts to broaden your search
Example: (fsa OR farm security administration)
Use * at the root of a word to find all forms of a word
Example: paint* will find painter, painters, painting, paintings
Use " " around a phrase to find just that phrase
Example: “personal space” will find that exact phrase only
Use ( ) to tell the computer which terms to connect with OR and which with AND
Example: (ecology OR “ecological issues”) AND (arizona OR southwest*)
