In 1917, Sjödahl and LDS Church Apsotle Hyrum M. Smith, who was the president of the church's European Mission, together worked on "A Commentary on the Doctrine and Covenants". While Sjödahl wrote most of the text, it was reviewed and approved by Smith. When "Doctrine and Covenants Commentary" was first published in 1919 in Liverpool, it was a church-approved publication and only Smith was listed as an author. However, subsequent publication of "Doctrine and Covenants Commentary" have acknowledged Sjödahl as its coauthor. "Doctrine and Covenants Commentary" is still cited frequently by Latter-day Saint authors and commentators.
