Reference books are a great place to start your search. Reference books provide an overview of a topic, typically just a few pages. If you take a few moments to skim a reference book, you'll get some great ideas on the key points on your topic that you can use for deeper research.
Reference books are shelved on the main floor of the library. The books must be used in the library, but because the entries are so brief, it is usually takes just a few minutes to jot down a few notes or make a list of relevant keywords.
