Advanced Searching in Tripod
1.) Keywords allow you to construct a search that reflects multiple issues in your research question. Building sets of related concepts and looking for their overlaps gives you more relevant and precise results. This approach is also called Boolean searching.
Related concepts (opium OR narcotic* OR opiate* OR drug*)
Tips: Enclose in parentheses
Capitalize the ORs
* ( Truncate) Searches root words with all the different endings; politic* = politics, politician, political, etc.
“ “ Enclose phrases in quotation marks, e.g. “china trade” to get the words together in that order
Overlaps (opium OR narcotic* OR opiate* OR drug*) (china OR chinese) (trade OR smuggl*)
Tip: Add the other related concept groups. Tripod automatically supplies the AND between groups
so that you see only titles that have at least 1 keyword from each of the 3 groups
Results (opium OR narcotic* OR opiate* OR drug*) (china OR chinese) (trade OR smuggl*) = 179 titles in Tripod
Results display automatically in relevancy order with the records having the highest number of keywords appearing first
Sorting for the newest books first shows recent scholarship
Sorting by oldest books is useful for finding primary sources
2.) Subject Headings allow you to find relevant material grouped together including titles that do not use the keywords you may have been searching.
Finding subject headings
Look at a book record in Tripod, check the subjects assigned to it, and choose whatever ones are relevant for your research.
Example: Gender and Mission Encounters in Korea : New Women, Old Ways.
by Hyaeweol Choi. University of California Press, 2009.
Women -- Korea -- History
Women missionaries -- Korea -- History
Women in missionary work -- Korea -- History
Refining subject searches
You can combine different concepts into a single subject search for precision. The results are more focused than a keyword search.
But all the words have to be terminology used in library subject cataloging.
To ensure this, you can use subject headings you have already found.
Combination subject and keyword search:
Searches both missionaries and missions
20th century added to specify the time period
3.) Other Databases
Other databases covering journal articles and primary sources also rely on advanced searching with AND and OR. Historical Abstracts and America History and Life work best if you build synonyms together in one box in parentheses, e.g. (trade or smuggl*) and leave the connectors as ANDs.
