In the 16th century, Onofrio Panvinio attributed the biographies after Damasus until Pope Nicholas I ( 858 – 867 ) to Anastasius Bibliothecarius ; Anastasius continued to be cited as the author into the 17th century, although this attribution was disputed by the scholarship of Caesar Baronius, Ciampini, Schelstrate and others.

The modern interpretation, following that of Louis Duchesne, who compiled the major scholarly edition, is that the Liber Pontificalis was gradually and unsystematically compiled, and that the authorship is impossible to determine, with a few exceptions ( e. g. the biography of Pope Stephen II ( 752 – 757 ) to papal " Primicerius " Christopher ; the biographies of Pope Nicholas I and Pope Adrian II ( 867 – 872 ) to Anastasius ).

Duchesne and others have viewed the beginning of the Liber Pontificalis up until the biographies of Pope Felix III ( 483 – 492 ) as the work of a single author, who was a contemporary of Pope Anastasius II ( 496-498 ), relying on Catalogus Liberianus, which in turn draws from the papal catalogue of Hippolytus of Rome, and the Leonine Catalogue, which is no longer extant.

Edward Gibbon's Decline and Fall of the Roman Empire ( 1788 ) summarised the scholarly consensus as being that the Liber Pontificalis was composed by " apostolic librarians and notaries of the viii < sup > th </ sup > and ix < sup > th </ sup > centuries " with only the most recent portion being composed by Anastasius.
