Databases can be searched similarly to how you would search in OneSearch or in the library catalog. Most databases are searchable by keyword or subject.
The link to SC4 Library's 200 + databases is http://esearch.sc4.edu/az.php.
As this image from the database Academic Search Complete's advanced search shows, you may search using Boolean operators (AND, OR, NOT) or by searching for any or all of your search terms.
You can also narrow down your results by publication date, by publication type, by full text, and by many other limiters which can aid in finding sources that are the best match for what you're looking for.
Results can be refined by language, author, document type, or others. Some databases mix scholarly and non-scholarly sources, and will allow you to limit between the two.
If you would like further assistance in searching the library databases, please contact a librarian or check out our guide "How to Use the Library Databases."
