The first comprehensive biography of Kim Il Sung was published in Korean in North Korea in 1968.
[7] A new version of Baik's biography was published in August 1972 as Ilyu haebang ŭi kusŏng Kim Il-sŏng wŏnsu (Marshal Kim Il-sung, Liberator of Mankind), prompted by the fact that the nascent Juche ideology had now been attributed to Kim Il Sung from his youth, which had to be written into the story.
[5] Baik devoted much of his work in the official biography to recount Kim Il Sung's struggle against the Japanese occupiers.
[9][10] Baik also omits any mention of Kim Il Sung's association with the Northeastern People's Revolutionary Army.
[11] It has also been suggested that "Baik Bong" is a pseudonym and that the writer lives in Japan.
