"'Good-natured Sven A. Wiman can manage a cautious grin when his married daughter relates...how when he returned home each evening from his part-time employment in various used book stores throughout Sweden he would produce an anti-Mormon book and then proceed to burn it. Sweden, you learn, has literally no end of anti-Church books, and Elder Wiman set himself up as a one-man cleanup committee to destroy as many of these diatribes against the Church as possible' (Deseret News, Church Section, May 16, 1953, p. 10).
"In 1965 we were visited by a student from Brigham Young University who had recently completed a mission for the Mormon
church in Texas. He related that while on his mission he was instructed to see that books critical of the Mormon church were removed from libraries. He said that he was told to take a set of new Mormon books—furnished by the church—to each library and offer them in exchange for their old books dealing with Mormonism. He said that the project was very effective in Texas, and that many of the critical books were removed from the libraries by this method. That such a project was actually carried out by some Mormon missionaries has now been verified by the Mormon writer Samuel W. Taylor. He stated:
"'...I wonder how many good-will tours by the Tabernacle Choir would be required to repair the damage done to the Mormon image when Playboy, with its enormous circulation and impact on young people, published the fact that Mormon missionaries were engaged in a campaign of book-burning? The item was a letter from a librarian of Northampton, Mass., Lawrence Wikander, published first in the American Library Association's Newsletter on Intellectual Freedom, May, 1963,...Wikander told of two Elders arriving at his library to inspect the index of Mormon material. They offered a list of "more up-to-date material" and after delivering it made the following proposition:
"'Now that we had these books which told the truth about their religion, undoubtedly we would like to discard other books in the library which told lies about the Mormon Church. Other libraries, they said, had been glad to have this pointed out to them.
"'Following the expose...a friend of mine tried to find out how extensive the missionary book-burning campaign had been. A number of returned missionaries from both domestic and foreign missions admitted that they had participated in it, but data as to when and how and by whom the project had been originated was, understandably, unavailable.
"'Self-appointed Comstocks among us have for years been dedicated to the unholy quest of seeking out and destroying books considered unfavorable.... My brother Raymond was approached by a zealot offering a number of rare Mormon books bearing library stamps; the devout saint blandly admitted stealing them to protect the public, but said he was sure that Raymond, would not be harmed' (Dialogue: A Journal of Mormon Thought, Summer 1967, p. 26)."
