For over a century, the LDS and RLDS (now Community of Christ) churches have had an interest in Nauvoo and Hancock County. Among Latter-day Saints, the Nauvoo period is seen as a kind of religious renaissance. It was there that Joseph Smith organized the Relief Society, clarified the nature of the temple and vicarious work for the dead, and forever altered the cosmological view of the Saints through sermons like the King Follett discourse. With so much interest today in what happened 170 years ago on the banks of the Mississippi, Kip Sperry's A Guide to Family History and Historical Sources in Nauvoo will surely be of great value to family historians and scholars for years to come. Sperry is a well-known family historian who has published and presented on numerous family history topics. He is currently Professor of Church History and Doctrine at Brigham Young University, where he specializes in family history. Sperry has collected all the disparate resources on Nauvoo into one place, creating a gargantuan volume that sets out to be "a guide to many articles and books that have been published describing various aspects of family history and historical research" related to Nauvoo and western Illinois (viii).
