This list covers all volumes of the Marx–Engels Cyclopedia. Alphabetization is letter-by-letter. Some standard abbreviations in general use may not be included.

Many of these abbreviations are used only in certain limited contexts, where their meanings are probably clear anyway. There is one extreme case, the letter E, which is used in three ways: for “Engels,” throughout the Cyclopedia; for “English” only after the entry titles in the Register; and for “East” in common geographical names.
