"The Oxford English Dictionary is the accepted authority on the evolution of the English language over the last millennium. It is an unsurpassed guide to the meaning, history, and pronunciation of over half a million words, both present and past. "
Reference sources provide background information on a topic, such as definitions of terms, key figures and events, and well written overviews. They can be a useful starting point for any research project. Your instructor will like these sources better than Wikipedia.
Examples of reference sources include: books, dictionaries, almanacs and encyclopedias. These sources are available in print and/or electronic formats.
