Vadim Rudnev’s “Dictionary of 20th Century Culture” contains articles on philosophy, psychoanalysis, linguistics, semiotics, poetics, versification and literature. The dictionary includes three types of articles - articles devoted to specific cultural phenomena of the 20th century, articles devoted to concepts that in the 20th century acquired particular relevance or were seriously rethought, and articles devoted to key works of art of the 20th century. The dictionary is made in the form of hypertext - this is realized through underlined words and phrases.
