The Seventh-day Adventist prophet Ellen Gould Harmon White (1827-1915) wrote all her letters and manuscripts by hand. These holographs were edited and polished by her secretaries. They corrected her grammar and spelling, deleted and substituted words and rearranged sentences. The holographs are only available to scholars who receive permission to see them at Adventist church headquarters in Silver Spring, Maryland. But facsimiles of many of these holographs have been published in various books and research documents. This books explores those holographs and shows what sorts of historical evidence can only be seen by examining those original documents. It also describes the revisions made after the first publication of some of her writings, most notably her first vision, her Testimonies for the Church and her book The Great Controversy. The historical evidence demonstrates that Ellen White's writings are not without errors and discusses the controversies that arose between those who were correcting her writings and those who claimed she made no errors. They believed her inspired writings should not be changed at all.
