27. Although all Catholics, especially the more learned, ought to denounce pernicious books either to the Bishops or to the Holy See, this duty belongs more especially to Apostolic Nuncios and Delegates, local Ordinaries, and Rectors of Universities. 28. It is expedient, in denouncing bad books, that not only the title of the book be expressed, but also, as far as possible, the reasons be explained why the book is considered worthy of censure. Those to whom the denunciation is made will remember that it is their duty to keep secret the names of the denouncers. 29. Ordinaries, even as Delegates of the Apostolic See, must be careful to prohibit evil books or other writings published or circulated in their dioceses, and to withdraw them from the hands of the faithful. Such works and writings should be referred by them to the judgment of the Apostolic See as appear to require a more careful examination, or concerning which a decision of the Supreme Authority may seem desirable in order to procure a more salutary effect. ARTICLE II OF THE CENSORSHIP OF BOOKS I. OF THE PRELATES INTRUSTED WITH THE CENSORSHIP OF BOOKS 30. From what has been laid down above (No. 7), it is sufficiently clear what persons have authority to approve or permit editions and translations of the Holy Bible. 31. No one shall venture to republish books condemned by the Apostolic See. If, for a grave and reasonable cause, any particular exception appears desirable in this respect, this can only be allowed on obtaining beforehand a license from the Sacred Congregation of the Index and observing the conditions prescribed by it. 32. Whatsoever pertains in any way to Causes of Beatification and Canonisation of the Servants of God may not be published without the approval of the Congregation of Sacred Rites. 33. The same must be said of Collections of Decrees of the various Roman Congregations: such Collections may not be published without first obtaining the license of the authorities of each Congregation, and observing the conditions by them prescribed. 34. Vicars Apostolic and Missionaries Apostolic shall faithfully observe the decrees of the Sacred Congregation of Propaganda concerning the publication of books. 35. The approbation of books, of which the censorship is not reserved by the present Decrees either to the Holy See or to the Roman Congregations, belongs to the Ordinary of the place where they are published. 36. Regulars must remember that, in addition to the license of the Bishop, they are bound by a decree of the Sacred Council of Trent to obtain leave for publishing any work from their own Superior. Both permissions must be printed either at the beginning or at the end of the book.
