Google Searching vs Library Database Searching
Database | |
Google is a search engine that indexes web pages from across the internet. It uses natural language algorithms that understand some meaning, so you can use more general search terms to get a wide range of results. For example, you might search for "books about race and ethnic relations among African Americans" in Google. |
Databases are specialized collections of information, often including scholarly articles, books, and other academic sources. Unlike Google, databases do not use algorithms and do not understand meaning. When searching in a database, it's important to structure keywords using a more specific and controlled approach. For example, you might search for "African Americans AND race relations AND books" in a database.

Consider your research topic, and write down several keywords that describe the various aspects of your topic.
Keep the following in mind when searching in a database.
Grow your keyword list with words you read in abstracts, article titles, and subject headings
Keep in mind that database searching is not an exact science, and you'll need to experiment with different combinations of keywords to get the best results.
Boolean Searching Explained
The "AND" operator narrows down search results by requiring all specified keywords to be present in the search results. It helps to find resources that include both terms, allowing for more focused and precise results. Examples:
Retrieves resources that contain both the words "race" and "ethnic relations." This search will locate sources specifically focused on the intersection of race and ethnic relations.
Finds resources that discuss the experiences of African Americans in relation to discrimination. |
|
The "OR" operator broadens search results by including either one or both of the specified keywords. It helps to find resources that include at least one of the terms, expanding the scope of the search and the number of results. Examples:
Retrieves resources that discuss either race or ethnicity. This search will broaden the scope and help students find materials that cover either concept.
Finds resources related to either Asian or Pacific Islander communities, helping students explore materials that address the experiences of these specific groups |
|
The "NOT" operator excludes specific keywords from the search results that contain certain terms, allowing for more targeted results. Examples:
Retrieves resources about race but excludes any that discuss nationality. This search can be useful when focusing specifically on the racial aspect of the topic.
Finds resources related to the broader Latino community but excludes materials that focus solely on Mexican experiences. |
