Encyclopedias
Encyclopedias are excellent sources for background information
on a topic.
As mentioned in module 3, there are two types of encyclopedias: general
and subject encyclopedias.
General Encyclopedias
General encyclopedias provide introductory information (such as a definition,
description, history, statistics) on a variety of subjects and may include
a brief bibliography at the end of each entry.
Subject Encyclopedias
Subject
encyclopedias concentrate on specific topics within a discipline (such
as education, philosophy, art, technology).
Like general encyclopedias, they include definitions, descriptive
information, history, statistics and detailed information on different
topics. Bibliographies featuring other materials on the topic are often
provided.
