Brittanica was the king of encyclopedias at that time, as far as I can remember. I had a set of those, and I remember comparing and finding other sets to be less good. I was pretty young but I spent a TON of time with them. I don't have experience with the Brittanica CDs but my guess is the content was of similar quality.
