Not all Databases are Full-Text
Some provide indexing and an abstract (a short summary of an article), but many do provide the complete text of an article online.
A word of caution: Don’t limit yourself to just those databases with full text. You could be missing some key articles on your topic by doing that.
Use Boolean Operators (AND/OR/NOT) to broaden or narrow your search.
AND--will narrow a search. All search terms must be in the record.
OR--will broaden a search. Either or both terms must appear in the record.
NOT--will narrow a search. The term following “not” won’t appear in a record.
Other search tips:
When You Locate a Good Article, look at the Descriptors or Subject Headings
That’s the special vocabulary used to describe the essence of an article. Use those words listed to locate other articles on the same topic.
You may also want to think of similar words or synonyms for your topic.
Check Databases for Related Subjects
If you're not finding information in the database you're looking in, try looking in a database for a similar subject. For example, if you're searching in a Psychology database about Educational Psychology, you might also try Education Databases.
