Identify the keywords and phrases you will use in your search for information on your topic. Use dictionaries and encyclopaedias and your textbook to define your keywords, or get brief information about a topic.
When you begin to research a topic, a good place to start is using Reference tools like:
1. Dictionary - to find the definition of terms (this will help define your topic);
2. Encyclopedia - to get general background information about a topic; and
3. Thesaurus - to find synonyms and other similar keywords (to use for searching).
