Keyword Searching
Keyword searching is used by internet search engines, databases, and the library catalog. Keep in mind that the search will find matches for specific words, not concepts. The default in the library catalog (and most databases) is find results that include every word in your search. Think of this as using AND between the words:
- English AND grammar AND study
- English grammar study
The two searches above are the same, and will find all books in the library catalog that have all three words in the description of the book.
If you want to find a specific phrase, with the words next to each other in order, use double quotation marks around the phrase:
- "English as a second language"
You might want to broaden your search to include synonyms or other related words. To find either of two words or phrases, use OR between them:
- ESL OR "English as a second language"
- EFL OR ESL
You can also use truncation to search for different forms of a word. The asterisk * is used in the library catalog and many databases for this.
- learn*
- learn* English language
- (learn* OR study) AND ESL
In the above searches, learn* will find the words learn, learned, learner, learners, learning, etc.
When combining searches, use parentheses () around different parts of the search, as in the examples above.
Subject Heading Searching
Think of subject headings as labels or tags that someone has used to identify the subject of a book or article. The subject headings are standardized so that only one term is used for a specific subject. Do you call it "Interior Design" or "Interior Decoration"? Following the Library of Congress Subject Headings standard, we use Interior Decoration in the STLCC Library Catalog. You can search directly by subject, or click on a subject heading in the description of a book you find by keyword searching. Instead of a list of search results, you'll get a list of subject headings to choose from. Here are a few examples:
