The database covers from 1963 to date. Most electronic databases can be searched by author, title words, subject or keywords. Some databases also have features which allow searching by specialized fields such as conference title. Many databases have a basic search screen for quick or simple searches and an advanced screen for more complex search strategies. Academic Index, Dissertation Abstracts, Education Abstracts and PsycInfo from the list above, have both a basic and an advanced search feature.
Most databases also allow searches to be limited by date or by language.
If a search yields too few results, or no results, consider broadening the topic. Eliminating one of the variables may also help.
