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.
