Two things of chief value in a cyclopedia are comprehensiveness and accuracy. And accuracy should be manifest in small things as in great. What has led to these observations is both a lack and a false statement in that in many respects excellent work, Lossing's "Cyclopedia of United States History," published by Harper Brothers. While mentioning some small sects which have left no stamp upon our history, except in some locality, it makes no mention of the Adventist bodies, the influence of which has been as wide as the nation. While mentioning William Miller, with more or less inaccurate statements as regards his work, it says that "he had between 30,000 and 40,000 followers, who called themselves 'The Church of the Latter-day Saints.'" It is known by every one well informed that this is the name adopted by the Mormons, and that the "Miller movement" was in no way connected with the Mormon movement. A historian guilty of such mistakes may well be doubted. The various Adventist bodies sprang from this so-called (yet worldwide) "Miller movement;" but none of them ever called themselves "Millerites." A true historian ought to have a standard in his own conscience which would prevent him from making such a mistake as that, a blunder so easy of correction. The worth of a cyclopedia is generally better tested by its accuracy in little things than in great.
