NOTE: In addition to the ratings, some of the evaluations contain a field entitled Público, which can be helpful in determining the appropriate audience for each book. For example:

• L-A1, público interesado: this would indicate a book of literature that does not contain any moral problems, but probably would not attract readers who don’t like works in that genre.
• P-B2, teólogos: this would be a work directed to theologians or students of theology, which, because of the complexity of the themes it addresses, could confuse readers with less background in the subject matter.
