Now that you have a Topic, you need to search for Sources to support your argument. Use your Topic Question for the Keywords you will use to find Books and Articles.
Your keywords are the meaningful subject words in your topic sentence.
Ex: Digital mammography; its uses and effect on breast imaging.
Think of new Keywords that are related to your Keywords.
Mammography; Mammogram; Breast Cancer Screening
Diagnostic Imaging, Radiography
Tomosynthesis, 3D Mammogram
Try different Keyword combinations when searching.
Use AND to link terms together and narrow your search:
Mammography AND Digital Imaging
Use OR to link terms together and broaden your search:
Mammography OR Mammogram AND Imaging
Use NOT to exclude irrelevant terms from your results:
Radiography OR Diagnotic Imaging NOT Dental
Use the Asterisk * (truncation) to search for different forms of a word:
Radiograph* searches for Radiography, Radiographer and Radiographic
Use Quotation Marks to keep Phrases together:
Once you've started finding articles on your topic (see the Finding Articles tab on where and how to search), look at the subject terms to get ideas of other keywords to search under. When you read the abstract, make note of additional terms to look up.
Make note of other studies, sources that may also round out your research. Use the databases to track down those articles.
