Encyclopedias, dictionaries, and other resources to help you discover basic information—names, dates, definitions, summaries, etc. These are good places to start when narrowing or choosing your topic, and when beginning research on an unfamiliar subject.
Use the Index volume to find your topic; this English translation is not in A-Z order because it follows the original Cyrillic alphabet order. Or consult the more comprehensive original (in the stacks AE55.B62) Bol'shaia sovetskaia entsiklopediia.
