Audio of a 2005 discussion between Robert Millet and Gerald McDermott, a professor of Religion and Philosophy at The Roanoke College Center for Religion and Society. The discussion is fairly technical on theological grounds, but there's some interesting exchanges about the differences between Mormons and Christians.
Brigham Young University’s Neal A. Maxell Institute for Religious Scholarship provides links to some of Robert Millet’s writings, including his article “The Book of Mormon, Historicity, and Faith” about why he thinks its important to Mormons that their beliefs be historically accurate.
The PBS programs Frontline and American Experience teamed up to produce a four-hour documentary about the history of the Mormon church. You can watch the complete series online, or read transcripts of many of the interviews they conducted.
This December 2007 survey by The Pew Forum on Religion & Public Life came out shortly after Republic presidential candidate Mitt Romney, a member of the LDS Church, gave a speech addressing concerns about his faith.
