Virtual reconstruction of a manuscript, which once probably contained the Book of Tobias (Tobit), the Book of Judith, the Book of Esther and the Book of Ezra. The palaeographical analysis suggests that the text was written in the Mondsee Abbey in the early 9th century. In the 15th century, several leaves from the original book were used as binding waste for Mondsee manuscripts.

In the 19th and 20th centuries, most of the fragments were detached from their host volumes, whereby the larger pieces (e.g. former pastedowns) were rebound in the soft fascicle Cod. 15346. Previous librarians of the ÖNB detached also smaller fragments such as sewing guards and tried to join pieces together to form partial leaves.
