In the twelfth century San Pietro extra muros remained under the jurisdiction of San Vincenzo al Volturno; therefore, there is good reason to believe that many of the liturgical manuscripts and other literary items arriving at San Pietro extra muros would come from a scriptorium in its parent monastery. San Pietro extra muros possessed an extensive collection of liturgical manuscripts; it had sixty-nine codices by the end of the thirteenth century. Some of these have survived to the present, specifically, as posited by Lepore, British Library Additional 5463 (an eighth-century Evangeliary), Biblioteca comunale, Macerata 378 (a Pontifical), Vatican Lat. 9820 (an Exultet Roll), and Ben 9, a ninth-century codex containing the Expositio in Apocalypsin (commentary on the Apocalypse) of Ambrosius Autpert.
