SUBJECT AND KEYWORD searches are not the same. The catalog uses controlled vocabularies for subjects. Keywords are natural language. If you find an appropriate book using a keyword find similar books by searching the same subject headings.
A CONTROLLED VOCABULARY like Library of Congress Subject Headings (LCSH) helps ensure the same topics are described using a formalized terminology. The terms are based on broad and narrow topics. Other controlled vocabularies include: Medical Subject Headings (MeSH), or LC subject headings for children's literature.
MARKING RECORDS enables you to save to a list then print or email a selected group of items.
A BIBLIOGRAPHIC RECORD in the online catalog will give important information including the title, author, publisher, publication date, subject headings and the Dewey decimal call number.
THE DEWEY DECIMAL SYSTEM is a classification scheme used to organize books. Other libraries may use the Library of Congress Classification System.
