Pseudonym Between Theory and Practice: The Contribution of Pseudonomastics to the Identification of Authors

Goal: The aim of this paper is to explore the phenomenon of pseudonymity from linguistic, cultural, historical, and practical perspectives, with a particular emphasis on the role of pseudonyms in literature, science, and library and information disciplines. The paper seeks to shed light on the mechanisms and motives behind pseudonymity, as well as the challenges it poses within cataloging and bibliographic processing. Approach/Methodology: The work relies on an interdisciplinary approach, combining theoretical knowledge from the fields of linguistics, literary studies, bibliography and history, with a comparative analysis of historical examples and classifications of pseudonyms. Special emphasis is placed on the role of pseudonyms in the modern digital environment and their importance for author identification in library systems. Results: The paper identifies key types of pseudonyms, the ways in which they are formed, and the reasons for their use throughout history. Pseudonyms are analyzed according to a number of criteria, including motives, duration, number, and recognizability. The role of pseudonyms as a complex library challenge in the cataloguing process is also highlighted. Limitations: The paper is theoretical in nature and primarily relies on existing literature and historical examples, while a lack of systematic studies on pseudonymity across various disciplines has been identified, leaving room for further research. Practical application: The findings of the paper are of particular importance to the library community, as they facilitate the understanding and classification of pseudonyms in the library catalog, thereby improving the accuracy and consistency of bibliographic processing. Social Significance: Knowledge of pseudonyms and their meanings contributes to the preservation of cultural and scientific heritage, and understanding this phenomenon has broader implications in the context of digital identity and freedom of expression in modern society. Originality/value: The paper presents a comprehensive theoretical overview of pseudonymity and pseudonomastics, supplemented by an analysis of contemporary and historical examples, thereby contributing to an under-researched field and encouraging further scientific research into this complex phenomenon.
