Decide on the types of sources

Different kinds of questions will require different types of information sources.

General databases such as Academic Search Premier contain current research from hundreds of scholarly and general publications on causes of violence and correlations with movies watched or music preferences.
National newspapers and news magazines covered current events, and parents or grandparents may be interviewed.
Industry Web sites and professional journals often cover average salaries and workloads. Local newspapers will have current employment information, and state and governemtn websites and statistical summaries will have unemployment information.
Consumer magazines report automotive safety and frequency of repair records, and local newspapers and specialty websites have current used car prices.
