The author points at some methodological problems connected with a dictionary of Bruno Schulz’s Polish, conditioned mostly by its implied audience. In comparison to other lexicographic projects, such a project would have to take into account the sources of the lexical items listed in dictionaries, their number in relation to the language as a sum total of such items, the ordering of Schulz’s vocabulary, and the meaning of words in his idiolect, compared to their commonly accepted meaning. The differences under consideration imply that even though the dictionary may prove useful in the research on common Polish – its history, linguistic norms, and semantics, in the first place it would meet the needs of both literary scholars and linguists specializing in Schulz. They would find in it well organized material to study the writer’s imagination, the linguistic world picture of his works, his style, his artistic inspirations, the ways of connecting ideas, and his linguistic mastery in general. Besides, such a dictionary would be helpful for common readers, as well as translators of Schulz into foreign languages and scholars from abroad. The theoretical assumptions and practical options involved will depend the primary goal of the project.
