Book "Neutral Bouyancy" by Tim Ecott

[Clifonef]

I'm a bibliophile newbie, so when I can't do, I read.    I just finished this book (more like a collection of magazine articles), and I liked it.  He talks a lot about the history of diving, but skips a lot of what I'd like to know more about, like how the regulator works, how they figured out how to mix gasses, how many war-time "frogmen" died, what kind of training does a SEAL get, plus a few more topics.

Those of you who are more experienced, how did you like it?  What other diving books are good reading?

What are the five best books on diving?

Thanks

PS  The Saint Paul Library (you know, the one that is open) has this book.  Call number is  GV838.672 E36 2001
