Book Smart: Your Essential Reading List for Becoming a Literary Genius in 365 Days (2007)). In 1920, Professor Erskine taught the first course based on the "Great Books" program, titled "General Honors", at Columbia University, and helped mould its core curriculum. The course, however, initially began to fail shortly after its introduction due to numerous disputes between senior faculty over the best way to conduct classes, as well as concerns about the rigour of the courses. This resulted in junior faculty, including Mark Van Doren and Mortimer Adler after 1923, teaching parts of the course. The course was discontinued in 1928, though later reinstated. Adler left for the University of Chicago in 1929, where he continued his work on the theme, and along with the university president, Robert M. Hutchins, held an annual seminar of great books with he later reworked into The Great Books of the Western World. University trustee and Chicago businessman Walter Paepcke was inspired by the seminar to found the Aspen Institute. In 1937, when Mark Van Doren redesigned the course, it was already being taught at St. John's College, Annapolis, in addition to the University of Chicago. This course was later named Humanities A for freshmen, and then subsequently evolved into Literature Humanities. Survivors, however, include Columbia's Core Curriculum, the Common Core at Chicago, and the Core Curriculum at Boston University, each heavily focused on the "great books" of the Western canon. Over 100 institutions of higher learning in the United States, Canada, and Europe maintain some version of a Great Books Program as an option for students. There are only a few true "Great Books Programs" still in operation. These schools focus almost exclusively on the Great Books Curriculum throughout enrolment and do not offer classes analogous to those commonly offered at other colleges. The first, and most well known, of these schools is St. John's College in Annapolis and Santa Fe (program established in 1937); it was followed by Shimer College in Chicago, the Integral Program at Saint Mary's College of California (1955), Thomas Aquinas College in Santa Paula, California (est. 1971), Thomas More College of Liberal Arts in Merrimack, New Hampshire (est. 1978), and Magdalen College of the Liberal Arts in Warner, New Hampshire. More recent schools with this type of curriculum include New Saint Andrews College in Moscow, Idaho (est. 1994), Gutenberg College in Eugene, Oregon (est. 1994), Harrison Middleton University
