If you’ve always wanted to read Wilford Woodruff’s journal but can’t afford ~$4k for the out of print nine-volume typescript edition, this is your best bet. Wilford Woodruff: History of his Life and Labors as Recorded in his Daily Journals, was written by Elder Matthias F. Cowley of the Twelve based on, and excerpting heavily from, Woodruff’s famous journals. It’s awesome. Get the free e-book on Project Gutenberg.
If you’re not sold yet, here’s the pitch: Wilford Woodruff’s life would be eminently worth reading about on its own account, and he also happened to be present for most of the important Church history events during his lifetime. This book thus reads like a combination biography/general history of the Church to 1890, and we get to read about much of that period in Wilford Woodruff’s own words. We hear about everything from baptizing hundreds to near-death experiences to the original pioneer journey to the Salt Lake Valley.
If that doesn’t sound interesting, I’m not sure what would. It would take a week of daily posting to do justice to my stack of excerpts, and they may get just that. But for now, go to Project Gutenberg, read the Preface, and try not to be intrigued.
