"During his days as Harvard’s influential president, Dr. Charles W. Eliot made a frequent assertion: If you were to spend just 15 minutes a day reading the right books, a quantity that could fit on a five-foot shelf, you could give yourself a proper liberal education. Publisher P. F. Collier and Son loved the idea and asked Eliot to compile and edit the right collection of works. The result: a 51-volume series of classic works from world literature published in 1909 called Dr. Eliot’s Five Foot Shelf, which would later be called The Harvard Classics." (Via) [more inside]
