Boolean operators are words (or, and, not) used to connect search terms to expand (or) or narrow (and, not) a search within a database to locate relevant information. Boolean operators are also called logical operators or connectors.
It is helpful to diagram the effects of these operators:
women or females
|Or retrieves records that contain any of the search terms. It expands the search. Therefore, use "or" in between terms that have the same meaning (synonyms) or equal value to the search.|
women and media
|And retrieves records that contain all of the search terms. It narrows or limits the search. Therefore, use "and" in between terms that are required to make the search specific.|
image not weight
|Not eliminates records that contain a search term. It narrows or limits the search. Therefore, use "not" in front of a term to ensure that the search will not include that term. Warning: Some databases use "and not" instead of "not." Check the database help screen.|

Wildcards & Truncation in the Library Catalog
Use the single asterisk * truncation symbol to search variations of a word, up to five characters, for example: critic* will also retrieve critics, critical, criticism. However, to truncate a word that could have more than five characters after the root word, use two asterisks **, for example: bank** will also retrieve banks, banking, banker, bankrupt, and also bankruptcy.
Evaluating Print & Electronic Resources
World Wide Web sites come in many sizes and styles. How do you distinguish a site that gives reliable information from one that gives incorrect information? Below are some guidelines to help.
For both print and Internet resources, consider:
Types of Web Sites: the url is a key
Find a Book on the Shelves
Check the Status field of the book's record in the catalog.
- IN LIBRARY - book is available for checkout.
- DUE + date - book has already been checked out.
The Location field shows the general location of the book.
- Most books are on the 2nd and 3rd floors.
- For other locations, check the location codes table.
- The Call # field gives the book's call number, which serves as the book's address in the library. Each row of books on the 2nd and 3rd floors will have a sign at the end indicating which call numbers can be found on that row.
How to Read Call Numbers
