At a crucial time in American history, John Tyler—elected vice president on the Whig ticket—became president upon the death of William Henry Harrison. The nation, after expanding across the continent, was suffering from sectional tensions, Indian conflicts, issues over slavery, and economic problems. Tyler's becoming president created a crisis for Whigs, who questioned his intentions, his past record, and his irregular political alliances. Soon, the course he set was unacceptable to both Whigs and Jacksonian Democrats. His presidency has not received the extensive scholarly study accorded many presidents. This bibliography provides an excellent beginning for those wishing to research Tyler and this critical period in American history.The definitive study of Tyler is yet to be written. Much of what has been written about him has been highly opinionated. Yet, as this bibliography reveals, primary material on Tyler is abundant. The volume presents in usable format most of the materials by and dealing with Tyler, including both secondary and primary materials. It also includes relevant information on his contemporaries and covers major works dealing with the period. It provides a good introduction to the literature of the times of Tyler.
