Reference sources can provide general background information (facts, definitions, dates, details), assistance in focusing your topic, quick access to important factual and statistical information, and references to other sources of information. It is therefore a good place to begin your research. Reference materials include almanacs, handbooks, encyclopedias, and dictionaries. Reference books are separated from circulating materials because of their important role in library research.
Few reference books are meant to be read from cover to cover. Instead, readers consult them for concise topic summaries in all subject areas, as well as for statistical, geographical, and biographical summaries. In addition, reference materials direct you to related sources and provide important supporting data in the form of statistics, definitions of technical terms, and tools for analyzing, broadening, or narrowing a topic.
The search for information on almost any topic might well begin and end in the Reference Collection. If the subject is completely new to you, a general encyclopedia is a good place to begin.
Once you know more, a subject encyclopedia can offer more specific background information on a topic from the perspective of a particular discipline such as philosophy, biology, or history:
Even consulting a subject encyclopedia on the Civil War may be too broad, and additional subject encyclopedias dealing with specific aspects of the Civil War might be necessary:
Encyclopedia articles often conclude with a list of sources for additional reading. Articles tend to include important names, dates, and events that may be associated with a topic and provide clues for further investigation.
This information can help you focus your topic, and can provide words that can be used as keys to other reference tools and to online databases, which in turn lead to books, articles, and other information sources.
