Specialized encyclopedias, dictionaries and other resources are useful for obtaining background information on a topic, in addition to helping you focus your topic and identify the main concepts, terms and keywords that describe your topic
Encyclopedias and dictionaries provide a general overview of a subject and information such as names, dates, and facts. They also provide historical and political events that may have impacted a person's work and the society and culture in which they lived and worked.
Dictionaries are useful for more than just looking up definitions. A historical dictionary, such as the Oxford English Dictionary, includes full etymologies, and dated quotations to show shifting meanings over time.
