La crítica textual y el Libro de Buen Amor

[Machine translation] The “Libro de Buen Amor” represents a good test for textual criticism, due to the multiplicity of problems it raises. In the light of the common errors method, the study aims to make a critical balance of the main, and most reasoned ecdotic approaches to the work of Juan Ruiz; of the oustanding questions, and of the future perspectives. It also dares to propose a few reflections on some controversial issues (the possible contamination of the branch T, the issue of the double redaction).
