Okay, so I checked my rom save files because I'm too lazy to plug the SNES or the PSX, so here are the title of the books.

The Guide of World Birds
The History of Shipbuilding
Buoyancy and it's Principles

The exact titles may vary depending on the versions (I'm pretty certain the third book is called "Principles of Buoyancy" in the PSX version), but those are close enough, I'd say.

And since I'm positive my answer is acceptable, I'm going to post a new question.

What is the Attack Power of Edge's Murasame?
