six years and $940,000 more later, on April 15, 1952, the Great Books of the Western World were presented at a publication party in the Waldorf-Astoria Hotel, in New York City. In his speech, Hutchins said, "This is more than a set of books, and more than a liberal education. Great Books of the Western World is an act of piety. Here are the sources of our being. Here is our heritage. This is the West. This is its meaning for mankind." The first two sets of books were given to Elizabeth II, Queen of the United Kingdom, and to Harry S. Truman, the incumbent U.S. President. Adler appeared on the cover of Time magazine for a story about the set of works and its idea index and inventory of Western topics of thought at large, of sorts. The initial sales of the book sets were poor, with only 1,863 sets sold in 1952, and less than one-tenth of that number of book sets were sold in 1953. A financial debacle loomed until Encyclopædia Britannica altered the sales strategy, and sold the book set through experienced door-to-door encyclopædia-salesmen, as Hutchins had feared; but, through that method, 50,000 sets were sold in 1961. In 1963 the editors published Gateway to the Great Books, a ten-volume set of readings meant to introduce the authors and the subjects of the Great Books. Each year, from 1961 to 1998, the editors published The Great Ideas Today, an annual updating about the applicability of the Great Books to contemporary life. According to Alex Beam, Great Books of the Western World eventually sold a million sets. The Internet and the E-book reader have made available some of the Great Books of the Western World in an on-line format. Volumes Originally published in 54 volumes, The Great Books of the Western World covers categories including fiction, history, poetry, natural science, mathematics, philosophy, drama, politics, religion, economics, and ethics. Hutchins wrote the first volume, titled The Great Conversation, as an introduction and discourse on liberal education. Adler sponsored the next two volumes, "The Great Ideas: A Syntopicon", as a way of emphasizing the unity of the set and, by extension, of Western thought in general. A team of indexers spent months compiling references to such topics as "Man's freedom in relation to the will of God" and "The denial of void or vacuum in favor of a plenum".
