I picked this book up -- this specific edition -- because I saw it was illustrated by the Dillons. This was fortunate because it turned out that, contrary to my previously held belief, I had not read it. What I had read as a child was some heavily edited-for-excitingness version almost entirely absent the encyclopedic accounts of marine life and oceanic conditions that constitute the bulk of the text. So few are the actual adventures of Nemo and the Professor and his two companions that I now wonder how they managed to get enough material to still have a book. The narration of the action is very understated, also, so I wonder if it was actually rewritten
for the volume I had.
With modern special effects this could make a great movie -- not an action film, but more like a marine documentary with strange asides into the human psyche.
