Subject-specific encyclopedias, along with providing important facts and topic overviews, can serve to familiarize with concepts and terminologies related to various topics. Often, encyclopedia articles will also include bibliographies or cited references lists at the end that can serve as additional sources of interest on a topic.
Encyclopedias are alphabetically arranged collections of articles that provide background information on key concepts, theories, and measures. Dictionaries provide definitions of words, thus helping to clarify terminology used in the field. Here are just a few databases that each search across hundreds of subject-specific encyclopedias and dictionaries.
