The Dictionary of Classical and Theoretical Mathematics, one volume of the Comprehensive Dictionary of Mathematics, includes entries from the fields of geometry, logic, number theory, set theory, and topology.
The goal in writing this dictionary has been to define each term rigorously, not to author a large and comprehensive survey text in mathematics.
