Within a database or online catalog, subject searching allows you to search by categories, which are found in the subject field of an item record. Subject terms are pre-defined and used for all items within a database or source that relate to that term.
For example, let's say you found the following article in a database:
Wilson, F. A., & Stimpson, J. P. (2010). Trends in Fatalities From Distracted Driving in the United States, 1999 to 2008. American Journal Of Public Health, 100(11), 2213-2219. doi:10.2105/AJPH.2009.187179
The subject terms associated with this article might include:
cell phones & traffic accidents,
traffic fatalities, etc.
By searching for the subject terms supplied by the database alongside this article, you may be able to find similar articles on this topic.
As with any search strategy, you may want to consider what subject searching is most useful for and anything you should be cautious about when using this searching technique:
