Specifically, of his complete short stories (six an- thologies) and the novel La otra raya del tigre (1977), a study that is part of the disciplinary fields of textual criticism and narra- tology as a theoretical and methodological procedure for the construction and analysis of the academic edition of the com- plete narrative of the mentioned writer, non-existent until now.
