Truman Madsen has done extensive research on the history and major events in the Prophet Joseph Smith's life. If this is the same as the cassette version I bought about 20 years ago, there are 8 different talks entitled "First Vision and Its Aftermath," "Spiritual Gifts," "Joseph's Personality and Character," "Joseph Smith and Trial," "Kirtland Temple," "Doctrinal Development and Nauvoo," "Teacher, Speaker, Counselor," "Last Months and Martyrdom." I have listened to these numerous times and never tire of hearing them again. I am glad they are still available to the public. I highly recommend this lecture series to anyone.
