Came across a few books that might be of interest. I am assuming these are now public domain but have no direct knowledge one way or the other. Last two published by the Navy have some nice photos. Can be downloaded as PDF files.

Published in 1946 so it even covers German efforts. Section VIII chapter on "Sneak Craft" describes mini-submarines, and some mention of WWII divers including Italy, Germany. There are a few mentions to Japanese swimmers. Word search Swim to find references to other sections covering diving.

Very cool find. Particularly enjoyed The World Beneath The Waves and the section on the history of diving apparatus.

Thanks for sharing those links. They are easy to use because they open in their own book format so you can read them at home or while waiting somewhere on a tablet or phone.

I'd like to express my gratitude too for bringing this online resource to our attention. I am familiar with the archive.org site, which takes "snapshots" of websites, showing how they evolve over time, but I didn't know that archive.org also offered books that could be perused in a book format.

A great find!

In case it was not obvious all these can be downloaded as PDF files.
