This comprehensive encyclopedia catalogs approximately 500,000 pseudonyms associated with around 270,000 individuals from various eras and fields. It includes not only traditional pseudonyms but also initials, nicknames, and names from orders, births, and marriages. The first nine volumes present real names alphabetically, along with details like birth and death dates, professions, and nationalities. The subsequent volumes link these pseudonyms to their real names, with professions translated into English for clarity, enhancing the identification of individuals across cultures and time periods.
