Canon 666

1. The fruit of an author's intellectual efforts is under the

protection of the law whether as the expression of the author's

personality or as the source of patrimonial rights. 2. Under

the protection of law are the texts of laws and the official acts

of whatever ecclesiastical authority and of their authentic collections; and therefore they may not be republished without obtaining the permission of the same or superior authority, and

observing the conditions laid down by it. 3. More detailed

norms about this matter may be issued in the particular law of

each Church sui iuris, in accordance with the civil laws concerning the rights of authors.
