12/22/20 I own the complete set (vol 1-54) and keep them at home on the top west shelf of my office; this includes The Great Conversation (which is volume 1) and The Great Ideas (volumes 2-3, the Synopticon); I also have at home Gateway to the Great Books volumes 2-5 (missing 1 and 6-10, see following paragraph). I have only the years 1979, 1981, and 1982 of The Great Ideas Today published each year 1961-1998. [I also have volumes 1-3 of Great Books of the Western World in the BCSA office, although I have them at home at the moment to read on my next sabbatical (Lord willing) as they seem a little nicer set (for reading).]

(Wikipedia) Gateway to the Great Books is a 10-volume series of books originally published by Encyclopædia Britannica Inc. in 1963 and edited by Mortimer Adler and Robert Maynard Hutchins. The set was designed as an introduction to the Great Books of the Western World, published by the same organization and editors in 1952. The set included selections – short stories, plays, essays, letters, and extracts from longer works – by more than one hundred authors. The selections were generally shorter and in some ways simpler than the full-length books included in the Great Books.

There's 1.5 sets here.
The first is a complete 54 volume set
The second is a compilation of books 1-26 All same 1952 production

The Great Books are all you need to give yourself a liberal arts education. I'm so happy to be adding this set of books to my shelf. ( )
