 Because of the extent of the damage, determining the text's type has been difficult for scholars.The manuscript was obtained by Alfred Chester Beatty in the first half of the 20th century, and published in "The Chester Beatty Biblical Papyri, Descriptions and Texts of Twelve Manuscripts on Papyrus of the Greek Bible" by Frederic G. Kenyon in 1933.In this work, Kenyon identified the text of the Gospel of Mark in formula_145 as Caesarean, following the definition of Burnett Hillman Streeter.
