LDS apostle George Q. Cannon states:

“The Journal of Discourses deservedly ranks as one of the standard works of the Church.”

~George Q. Cannon, Journal of Discourses (London, England: Amasa Lyman, 1860), Volume 8, iii, “Preface.”

Yet even the church admits the 26-volume digest has some significant mistakes, still, they are reticent to discuss which portions are actually wrong; giving the student of Mormonism doubt about its reliability as a whole.
