Search Strategies

Keyword Searching The default for the library catalog and most databases is a keyword search. This searches the cataloged fields of a record (generally including title, author, subject headings, description, and abstract, if applicable). 

By selecting Advanced Search, you can be more specific with what you are looking for: if you have a title, author, or subject in mind, you can search just those fields, as well as narrow down your search by date or material type at the beginning of your search.

Search Tips

Phrase Searching adding quotes to your phrase will search for an exact combination of words: "Emergency Preparedness" or "Law and Order"

 

Truncation To truncate means to cut off a part, or to chop short.

When we truncate a word in a search, it allows the database to search for words with multiple endings and get additional results.

 

OR To expand your search for more than one keyword at the same time, add the boolean operator OR. For example, wages OR salary would return any results with either keyword in the record.

 

NOT to exclude a word from your search, enter the boolean operator NOT before it. For example, test NOT drug would return any results with the keyword test, while excluding results with the keyword drug.

Subject Headings

Subject headings 

Under the Details tab in the catalog, you'll see information including title, author, creation date, and subject headings. Subject headings are assigned to books, and other library materials to connect like resources.

Once you have found one resource that could be useful, check out the subject headings it's been assigned. Clicking on these subject headings can link you to additional relevant sources of information.
