Folklore Encyclopedias & Dictionaries
General and specialized encyclopedias and dictionaries are an excellent place to begin collecting background information on a topic. They typically provide a concise overview as well as a bibliography of core works. There are many specialized encyclopedias and dictionaries relevant to folklore. Some of these include information on Slavic folklore. Reference works will lead you to other reliable sources on a topic. This strategy often can be more effective than database searching because relevant sources have already been identified and vetted for quality.
