Reference works such as dictionaries, encyclopedias, directories, and wikis are generally not thorough enough to provide you with the detailed information that you need from a resource. However, they can provide useful background information.

Introductory resources explain in general terms what 's currently known about your topic and help you understand the broader context of your research.
