The present volume is a radically revised and enlarged edition, with over 2,000 new entries and a new introduction. A new appendix is devoted to terms relating to pseudonymous and changed names. More emphasis has been put on the change of an individual's first name, as well as his or her surname, since an adoption of this kind is similar to the taking of a new family name. In many cases the accompanying details or quoted material have been expanded. Arranged by pseudonym, the entries give the true name, vital dates, country of origin or settlement, and profession. Many entries include the story behind the person's name change.
