In 1889, John A. Broadus delivered the Yale Lectures on Preaching (Lyman Beecher Lectureship on Preaching) at Yale University's Marquand Hall Chapel. These lectures were unpublished, and for many years they were known as the "Lost Yale Lectures." The manuscripts were discovered in the midst of processing the John A. Broadus Papers in approximately 2001, and they were subsequently digitized by a PhD student writing his dissertation on John Broadus. For additional information and analysis, see Mark M. Overstreet, "The 1889 Lyman Beecher Lectures on Preaching and the Recovery of the Late Homiletic of John Albert Broadus (1827-1895)" (Ph.D. diss, SBTS, 2005).
