Good background information may be found in reference sources. The Internet Encyclopedia of Philosophy is an excellent starting point.

Reference sources (dictionaries, encyclopedias, manuals, guides) provide the following types of information on virtually any topic:
- Reliable background information;
- Articles written by subject experts;
- Dates, timelines, events, people, definitions related to your topic;
- Statistics;
- A list of further readings, normally found at the end of encyclopedia articles. Use these references as springboards for further research.
Using the Encyclopedia of Ethics may also be of help.
