The type of source you use often depends on the type of information you need. A factual-type question might be best answered by a reference book, such as an encyclopedia or almanac. In contrast, a large research project might require using online article databases to find scholarly journal articles. General collection books on a specific topic may aid in synthesizing material and add context to a subject. Web resources are useful for finding current news information, while print sources may be better for more stable or historical topics. When researching, select a variety of sources to ensure different viewpoints on a topic.
