The title "Liber Pontificalis" goes back to the 12th century, although it only became current in the 15th century, and the canonical title of the work since the edition of Duchesne in the 19th century; in ancient manuscripts it is referred to as Liber episcopalis in quo continentur acta beatorum pontificum Urbis Romae, and later the Gesta or Chronica pontificum.
During the Middle Ages, Saint Jerome was considered the author of all the biographies up until those of Pope Damasus (366–383), based on an apocryphal letter between Saint Jerome and Pope Damasus published as a preface to the Medieval manuscripts. The attribution originated with Rabanus Maurus and is repeated by Martin of Opava, who extended the work into the 13th century. Other sources attribute the early work to Hegesippus and Irenaeus, having been continued by Eusebius of Caesarea.
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 turns draws from the papal catalogue of Hippolytus of Rome, and the Leonine Catalogue, which is no longer extant. Most scholars believe the Liber Pontificalis was first compiled in the 5th or 6th century.
Because of the use of the vestiarium, the records of the papal treasury, some have hypothesized that the author of the early Liber Pontificalis was a clerk of the papal treasury. Edward Gibbon's Decline and Fall of the Roman Empire (1788) surmized the scholarly consensus as being that the Liber Pontificalis was composed by "apostolic librarians and notaries of the viiith and ixth centuries" with only the most recent portion being composed by Anastasius.
Duchesne and others believe that the author of the first addition to the Liber Pontificalis was a contemporary of Pope Silverius (536–537), and that the author of another (not necessarily the second) addition was a contemporary of Pope Conon (686–687), with later popes being added individually and during their reigns or shortly after their deaths.
Pope Adrian II (867–872) is the last pope for which there are extant manuscripts of the original Liber Pontificalis: the biographies of Pope John VIII, Pope Marinus I, and Pope Adrian III are missing and the biography of Pope Stephen V (885–891) is incomplete. From Stephen V through the 10th and 11th centuries, the historical notes are extremely abbreviated, usually with only the pope's origin and reign duration.
Duchesne attributes all biographies from Pope Gregory VII to Urban II to Pandulf, while earlier historians like Giesebrecht and Watterich attributed the biographies of Gregory VII, Victor III, and Urban II to Petrus Pisanus, and the subsequent biographies to Pandulf. These biographies until those of Pope Martin II (1281–1285) are extant only as revised by Petrus Guillermi in the manuscripts of the monastery of St. Gilles having been taken from the Chronicle of Martin of Opava.
Early in the 14th century, an unknown author built upon the continuation of Petrus Guillermi, adding the biographies of popes Martin IV (d. 1281) through John XXII (1316-1334), with information taken from the "Chronicon Pontificum" of Bernardus Guidonis, stopping abruptly in 1328.
The entries for the first three centuries are probably most useful to historians as examples of what was known in the 5th century about the early church. From the 4th century forward the compilers are on more secure ground, though there are still obvious discrepancies and mistakes. Textual examination suggests that there were two early versions before the siege of Rome in 546, after which the Liber Pontificalis was untouched. From the early 7th century (roughly the time of the pontificate of Honorius I) forward until the pontificate of Adrian II the entries are contemporary, added shortly after the death of each pope, and, although reflecting biases of the authors, are at least reasonably accurate.
The Liber Pontificalis was first edited by J. Busæus under the title Anastasii bibliothecarii Vitæ seu Gesta. Romanorum Pontificum (Mainz, 1602). A new edition, including the Historia ecclesiastica of Anastasius, was edited by Fabrotti (Paris, l647). Another edition, editing the older Liber Pontificalis up to Pope Adrian II and adding Pope Stephen VI, was compiled by Fr. Bianchini (4 vols., Rome, 1718-35; a projected fifth volume did not appear). Muratori reprinted Bianchini's edition, adding the remaining popes through John XXII (Scriptores rerum Italicarum, III). Migne also republished Bianchini's edition, adding several appendixes (P. L., CXXVII-VIII).
Modern editions include those of Louis Duchesne (Liber Pontificalis. Texte, introduction et commentaire, 2 vols., Paris, 1886-92) and Theodor Mommsen (Gestorum Pontificum Romanorum pars I: Liber Pontificalis, Mon. Germ. hist., Berlin, 1898). Duchesne incorporates the Annales Romani (1044–1187) into his edition of the Liber Pontificalis, which otherwise relies on the two earliest known recissions of the work (530 and 687). Mommsen's edition is incomplete, extending only until 715. Translations and further commentaries appeared throughout the 20th century.
