This is the e-book version of Mary-Anne Vetterling's bibliography for Juan Ruiz's Libro de buen amor, now in its third edition. It is a research tool for scholars working on the Libro de buen amor (LBA) (Book of Good Love) and contains an extensive listing of almost all publications on that 14th century Spanish classic, plus a history of the creation of this bibliography, listings of contributors, editions of the LBA, other bibliographies on the LBA, and incorrect references. It is periodically updated. This e-book is searchable and works well in tandem with the print version of this bibliography also by Mary-Anne Vetterling.
