Most of the books weren't very good though. They tended to be glorified audiobooks and didn't make effective use of the technology.
By far the best one I ever saw was the sample book that came with my family's Quantum Leap. It was quite thick and had a wide variety of different topics, all of which were extremely well produced, and every page was filled with things to explore. As a child, I particularly liked the pages on US presidents (including well-known quotes or recordings of many of them), Europe (with the national anthems of every European country and memory games to learn each country), and the super cool Parts of the Body (with translucent pages showing each layer, and funny sound effects when you explore each body part).
Some of the Magic School Bus books were decent too. The Solar System in particular had excellent games—you wouldn't think audio-only games pointing at a static page would be very fun, but some of them were very creative.
