Wouters, Manual of Moral Theology
Vol. I, Bk. II, Tr. II, Diss. II, Pt. IV, Sect. II, Ch. II, Article II. On Books Prohibited by Particular Decree
What authority can prohibit books, we said in n. 1118. But here there is discussion only of books which are prohibited by the Apostolic See, and so are inserted into what is called the Index of Prohibited Books. Moreover, that Index, revised by Leo XIII and promulgated in the year 1900, was published several times and again in the year 1929. For the rest, note:
I. The Apostolic See prohibits books either by itself, i.e. through Apostolic letters of the Roman Pontiff, or with the help of a Congregation. Moreover, formerly this business belonged to the Congregation of the Index, but now to the Congregation of the Holy Office, which undertook that function after the prior Congregation was suppressed1 (can. 247, § 4).
II. With respect to the interpretation of particular prohibitions, note:
Whenever all the writings of some non-Catholic author are prohibited, only those works are understood which either treat of religion, or have been proscribed by some general or special decree. Whenever all the writings of some Catholic writer are forbidden, only those works are touched by the prohibition which are prohibited by some general or special decree.2
If the first or earlier volumes of some work are placed in the Index, and the later volumes have followed that decree of prohibition into public light; or if periodical booklets are proscribed which afterwards have been continued again and again; or if all the works of some writer are prohibited, and he has published other works after the decree was issued: in all these cases the volumes or booklets or works made public after the last special decree, although they are not comprehended by that special decree, nevertheless are held suspect, and are deservedly presumed to fall into the prohibition of some decree from the general ones, unless perhaps the author's recovery of sound sense is established.3

Books of Indulgences
"Whether in decree no. 17 of the General Decrees concerning the prohibition and censure of books recently issued by Our Most Holy Lord Pope Leo XIII, these words: let them not be published without the permission of the competent authority, are to be understood in such a way that henceforth all books, booklets, sheets, etc., of indulgences are to be referred only to the Ordinaries of places in order to obtain permission? Or are they to be subjected to the review either of the Sacred Congregation of Indulgences or of the Ordinary of the place according to the norms established before the new Constitution Officiorum ac Munerum? - Response. To the first part: Negative. - To the second: Affirmative." Sacred Congregation of the Index, 7 August 1897.
"Article 12, section 3, of the Decrees issued after the old Rules of the Index is to be understood in such a way that, if there is question of publishing the grant of some indulgence, or a summary of indulgences which is to be taken from an Apostolic Brief or Rescript, or a summary already published by authority of the Sacred Congregation, it is within the power of the Ordinary to grant permission to print the grants of those indulgences (provided that there is not a special and express prohibition for some list); but, on the contrary, if there is question of a summary previously collected but never approved, or now to be collected for the first time from various grants, the express permission of the Sacred Congregation of Indulgences is required. His Holiness approved." Sacred Congregation of Indulgences, 22 January 1858.

Vol. II, Treatise On Censures, Ch. II, Namely: 1. on Excommunicat…, Art. I, Appendix I. On the Crime of Heresy, the Reading of Depraved Books, and the Index
III. On the Index of Prohibited Books
- The Index was composed and promulgated by command of Paul IV in the year 1558; Pius IV perfected it with the Council of Trent and published it in the year 1564. Clement VIII enlarged it in the year 1595. The Congregation of the Index was instituted by St. Pius V. See St. Alphonsus, Appendix On the Prohibition of Books, book 1, at the end, no. 17, etc.
The Index presents three principal classes of prohibited books. The first class contains all books of heretics which contain heresy or treat expressly of Religion. The second class embraces books of Catholics against the Faith or good morals. The third class contains books published without the name of the author which hand down depraved doctrine. St. Alphonsus, no. 289.
Books of the first class, which by the ancient law were all prohibited under penalty of excommunication, still all remain prohibited; but which are now forbidden under penalty of excommunication, and indeed a reserved one, was said above. Books of the second and third class are not considered prohibited unless they are specially designated in the Index, unless nevertheless they pertain to certain general classes of matters which are designated in the Rules of the Index. Furthermore, in the Index all books of heresiarchs are prohibited generally in hatred of the author, even if they do not contain heresy or treat of Religion 4.
4 Avanzini notes (Commentary, no. 8) that, with account taken of penalties, books prohibited or to be rejected can be divided into three classes, namely: 1. books prohibited under penalty of excommunication reserved to the Roman Pontiff, concerning which above, no. 972, II; 2. books prohibited under penalty of fault according to the Index of Prohibited Books and its rules in force. To this class can also be referred books or writings forbidden only by the law of nature, although not yet placed in the Index, which nevertheless can otherwise easily be referred to certain general classes of prohibited books; likewise, books prohibited by Bishops in individual dioceses. That Decree, however, both as regards the force of a positive precept and as regards the censure, if any were added, would bind only the subjects of each diocese. 3. Books which, according to the ancient usage in the Church, we shall call apocryphal, which, namely, we hold as destitute of all that authority, force, or use to which they might appear to be ordained. In this class we call a monument, canon, testament, decree, etc., apocryphal; but the Church simply repudiates these books without any sanctioned penalty. Of this kind are books treating of sacred matters but printed without the approval of the Ordinary. To this class can be referred all books of indulgences, journals, summaries, pamphlets, and sheets in which their concessions are contained but which were published without permission of the Sacred Congregation of Indulgences; likewise ritual books issued without the approval of the Congregation of Sacred Rites, etc.
Principal Rules of the Index Issued by Command of the Council of Trent
- All books condemned before the year 1515 are prohibited, even if they are not found described in the Index.
- All books of heresiarchs are altogether forbidden, even if not erroneous or not treating expressly of Religion. Other books of heretics which are not erroneous and do not treat of Religion can be permitted, provided they have been examined and approved 5.
5 This clause does not appear now to be in force.
- The Scriptures and books of controversies in the vernacular language cannot be read unless they have been approved by the Holy See or published with notes taken from the holy Fathers of the Church or from learned Catholic men 6.
6 POSTULATUM. Since it has been reported with certainty to the Sacred Congregation of the Index that in some places the most sacred books of the Bible are printed in the vernacular language without the most salutary laws concerning this matter being observed, and since it is therefore to be feared that, such being the conspiracy of wicked men especially in these times, errors wrapped in the more sacred array of the divine word may be insinuated perversely, the same Sacred Congregation judged that those things which were otherwise decreed must again be recalled to the memory of all: namely, that vernacular versions of the Bible are not to be permitted unless they have been approved by the Apostolic See or published with annotations taken from the holy Fathers of the Church or from learned Catholic men. 13 June 1757. Likewise, 7 January 1836.
- Books treating expressly of obscene things are absolutely prohibited, although they are not found in the Index.
- Likewise, all books treating of astrology, divination, and sorceries are forbidden, more probably under an excommunication not reserved.
- All books condemned on account of suspicion of false dogma are prohibited under penalty of excommunication, but see above, no. 972, II; others under guilt of mortal sin.
Besides the ten Rules issued by command of the Council of Trent, there exist other general Rules established by the Sacred Congregation of the Index itself and published by command of the Pontiffs in the volume of the Index of Prohibited Books, under this title: Decrees Concerning Prohibited Books, etc.

167. Understand the clause as All works, where another is not indicated; but the day as the day of the last decree, if the writer has been condemned several times.
Where by decree there is proscribed not the very universality of the works but a work whose title is general, for example All works, the words "All works" are written in ordinary letters and within parentheses. But if at any time that proscription seemed to be equated to a universal and collective one, we have prefixed to the name of the writer the sign *.

Vol. I, Special Moral Theology, Treatise: On Divine Faith, Fourth Part: On the Vices …, Question Two: On Sins Indi…, Article III: On the Reading and Dissemination of Prohibited Writings
774. Special prohibition of writings. - Apart from books prohibited by the general rules, some are also specially and by name entered in the Index, or prohibited in another way by the Apostolic See. This prohibition brings about:
- that all editions already made are prohibited, unless the prohibition is limited to a determined edition;4 likewise all future editions "unless, corrections having been made, he who had prohibited the book, or his superior or successor, gives permission" (can. 1398, § 2);
4 Prohibitions which forbid books on account of matter are judged to regard all editions; prohibitions which forbid books on account of defect of approval are not extended to books previously published.
- that all versions are prohibited, for "the prohibition of books brings it about that without due permission a book cannot... be translated into another language" (can. 1398, § 1), unless nevertheless only the version had been entered in the Index;
- that if all the works of some author are prohibited, they are to be understood not as later works, but as the earlier ones which exist at the moment of condemnation. From the preface of the Catalogue of the Index published in the year 1940 we have in addition that "when all the works of some writer are condemned, all and each of the same writer's works are judged condemned," and not only those which are prohibited by the general rules. Since this norm is modifying, it does not have retroactive value, so that for condemnations issued before January 2, 1940, all works are only those which are prohibited by the general rules. Nevertheless, a presumption and suspicion is present against the others, whence in practice they are to be submitted to examination.
- that if all the love-stories of someone are prohibited, all and each are also understood if the condemnation was issued after the year 1940; otherwise only those which are prohibited by the general rules.
- that chrestomathies are also prohibited if they reproduce one or more condemned writings for the greater part.

Concina, Compendium
Bk. III, Diss. I, Chapter X — On prohibited Books
VIII. In the Tridentine and Roman Index, besides the books of the Heresiarchs, many books of Catholics are prohibited. The former are named of the first class, the latter of the second. Those books of Catholics are prohibited which contain errors hostile to the doctrine of faith or of morals, or which instill a suspicion of error, or offend pious ears, or furnish scandal, or contain lax opinions. Books of this class are sometimes prohibited until they be corrected. This happens when in the book absolutely sound doctrine is contained, but some proposition, which is not capital, has fallen from the author's pen beside his intention, or from a slip of the mind, or through ignorance. Such books are prohibited under mortal sin, and an excommunication not reserved.
