Searching with

Keywords, Boolean operators, Truncation

And

### Choosing Keywords

• What discrete (separate or distinct) ideas or concepts make up or are contained within your research question?

• What are the effects of TV violence on children?

• Children AND violence AND television

### Keywords

• What are some synonyms or closely related words or phrases for each of the terms?

• Children

• Children OR Youth OR Teenagers

• Violence

• Violence OR Aggression OR Hostility

• Television

• Television OR TV OR Media

### Combining keywords with Boolean operators

• AND joins discrete terms to narrow a search

• OR joins synonyms to broaden a search

• NOT excludes terms to narrow a search

• Parentheses organize search terms (like math)

Effective: (5+9) – (6+3) = 5

Not so effective: 5 + 9 – 6 + 3 = 11

### Combining keywords with Boolean operators (cont’d)

AND

(violence OR aggression OR murder)

AND

(television OR tv OR media)

### ***Truncation***

• Use an asterisk (*) to cut off words at root

• Find words that have the same root but different endings

• Example: robot*

robot, robots, robotic, robotics

### In Class Exercise

• Break into groups

• Follow instructions on the handout

### Cherry Picking Strategy

• Use Keyword searching to find one good item that is directly about your topic.

• Ex: Native Americans in Movies

• Find the Subject Heading in the record for that item.

• Indians in Motion Pictures

• Search on that term as a subject to bring up more items on the same topic.

### Library of Congress Subject Headings

• These are subject terms decided on by the Library of Congress that bring together all works on a particular topic.

• Heart attacks or Myocardial Infarctions?

• Native Americans or Indians or First Nations?

• Capital Punishment or Death Penalty?

• LC will pick one term for each concept

• Try browsing LCSH

### Be specific

• When searching with LCSH look for the most specific term that fits your topic.

• Works on more specific aspects of a topic will be with the most specific term

• Divorce

• Divorced Parents

• Children of Divorced Parents
