CHAPTER IV.
Of Printers and Publishers of Books.
43. No book liable to ecclesiastical censorship may be printed unless it bear at the beginning the name and surname of both the author and the publisher, together with the place and year of printing and publishing. If in any particular case, owing to a just reason, it appears desirable to suppress the name of the author, this may be permitted by the ordinary.
44. Printers and publishers should remember that new editions of an approved work require a new approbation; and that an approbation granted to the original text does not suffice for a translation into another language.
45. Books condemned by the Apostolic See are to be considered as prohibited all over the world, and into whatever language they may be translated.
46. Booksellers, especially Catholics, should neither sell, lend, nor keep books professedly treating of obscene subjects. They should not keep for sale other prohibited books, unless they have obtained leave through the ordinary from the Sacred Congregation of the Index; nor sell such books to any person whom they do not prudently judge to have the right to buy them.
CHAPTER V.
Of Penalties Against Transgressors of the General Decrees.
47. All and every one knowingly reading, without authority of the Holy See, the books of apostates and heretics defending heresy; or books of any author which are by name prohibited by Apostolic Letters; also those keeping, printing, and in any way defending such works; incur ipso facto excommunication reserved in a special manner to the Roman Pontiff.
