Literature: Articles

Many (but not all) databases allow subject searching. A subject search is more specific than a keyword search: it looks in only one field of each record - the subject field. 

Subject searching uses specific terms, known as subject headings, that describe the content of the document (book, article, video, map, etc.). The subject headings come from a predetermined list of possible terms known as the database's thesaurus. The linking between the subject headings and the documents in the database is known as the subject indexing. 

Many databases use subject headings that are unique to that particular database. This controlled vocabulary allows for consistency of subject terms across the database. Most databases that use subject indexing provide a way to search the thesaurus. In the thesaurus, subjects are often listed with broader, narrower, or related subjects. Using the database's thesaurus will help you identify most effective search terms.

Keywords are words that describe your topic of research. These can be individual words or a phrase. In a keyword search, you want to search for the main concepts or synonyms of your keywords.

A field is a specific part of a record in a database. Field searching is a technique that can help focus your search that allows you to communicate to databases telling them exactly where you would like your keywords to be found. Common fields that can be searched are author, title, and subject.

The Gale Literary Index can be used to search for the information on authors and titles contained in Gale publications, many of which are contained in the Library Book Collection. The results of a search will show you which Gale series, volumes and page numbers to select to find the information you need.
