"The preeminent book in the line of Watts, Rippon, and supplements was the work of James M. Winchell (1791-1820), the short-lived pastor of First Baptist Church, Boston...Adopting Rippon's approach to meeting all the needs of worshippers, Winchell and his successors also made the supplement of 327 hymns available separately and provided a complimentary tunebook." - Music & Richardson, "I Will Sing the Wondrous Story", p. 163.
