The author of the paper attempted to show that occurring of such new research areas of author’s lexicography as onymography and poetonymography is determined by the general trends of the development of this scientific field. Comparative and taxonomic methods have been used in the paper. Language entries in different dictionaries have been compared, their components have been described, methods of onym lexicon description have been collated. Methods of onym lexicon description depend on conception of author’s dictionary and special features of poetics and style of literary works which is analyzed. The general trend of contemporary author’s lexicography is to describe discrete components of writer’s language. Proper names are one of these components.
