No book shall be printed without the author's name in full, together with his nationality, upon the title-page. If there be sufficient reason for giving an anonymous work to the world, the censor's name shall stand for that of the author. Compilations of words, sentences, excerpts, etc., shall pass under the name of the compiler. Publishers and booksellers are to take care that the printed work agrees with the MS. copy as licensed, and to see that all rules with regard to the author's name and his authority to publish have been observed. They are, moreover, to take an oath before the Master of the Sacred Palace in Rome, or before the bishop and Inquisitor in other places, that they will scrupulously follow the regulations of the Index. The bishops and Inquisitors are held responsible for selecting as censors, men of approved piety and learning, whose good faith and integrity they shall guarantee, and who shall be such as will obey no promptings of private hatred or of favor, but will do all for the glory of God and the advantage of the faithful. The approbation of such censors, together with the license of the bishop and Inquisitor, shall be printed at the opening of every published book. Finally, if any work composed by a condemned author shall be licensed after due purgation and castration, it shall bear his name upon the title-page, together with the note of condemnation, to the end that, though the book itself be accepted, the author be understood to be rejected. Thus, for example, the title shall run as follows: 'The Library, by Conrad Gesner, a writer condemned for his opinions, which work was formerly published and proscribed, but is now expurgated and licensed by superior authority.'
