Awhile back, Jim Christley (I think) wrote a review about "Beneath The Surface:submarines built in Seattle & Vancouver, 1909-1918" by Bill Lightfoot and published by Canadian Books.
It's been republished by Green Board Press under the title "Beneath the Surface:World War I Submarines Built in Seattle and Vancouver". Lots of pictures and drawings. A must have for the W.W. I sub fans or those interested in general sub history.

I'm, in no way, connected to the publisher or author, I just happened to pick up a copy at the Sub Vets convention (last week) and liked it.
