Section IV treats the issues connected with the actual publication of liturgical books. The first of seventeen numbered sections:
109. Of the liturgical books of the Roman Rite containing only Latin texts, only the one published by decree of the Congregation having competency at the time is designated the “editio typica”.[79] The editiones typicae published prior to this Instruction were issued either Typis Polyglottis Vaticanis or by the Libreria Editrice Vaticana; in the future, they are usually to be printed by the Tipografia Vaticana, while the right of publication is reserved to the Libreria Editrice Vaticana.
