About Verse & Variance
Verse & Variance is an open research tool for studying the textual history of the Book of Mormon. It brings together eight published editions (1830–2013), character-level change tracking, interactive timelines, and analytical dashboards — all freely available in your browser.
Our mission
Textual scholarship thrives on transparency and accessibility. Our goal is to make it easy for researchers, students, and curious readers to see exactly what changed between editions of the Book of Mormon — and to explore those changes through rich, interactive visualizations rather than static tables or footnotes.
What you can do here
- ●Read & compare — view any chapter across all eight editions with character-level diffs highlighting every change.
- ●Explore timelines — follow the Book of Mormon's narrative chronology, the translation process, and key events in early church history.
- ●Browse all changes — filter verse-level differences by book, edition pair, or change type with full-text search.
- ●View analytics — charts covering revision patterns, text metrics, gendered language, sentiment, and a vocabulary comparison with the King James Bible.
Data & methodology
All text is derived from the BYU Open Scripture word-aligned TSV files. Verses follow modern chapter/verse references (1879+) across all editions so that parallel comparison is straightforward. Character-level diffs are computed algorithmically; change classifications (spelling, grammar, punctuation, substantive) are derived from automated heuristics and should be treated as approximate.
Open source
Verse & Variance is open source. Contributions, bug reports, and feature suggestions are welcome. If you spot an error in the data or have an idea for a new visualization, we'd love to hear from you.
