The U.S. Naval Institute Press publishes them. I had most of that info ready for posting but lost everything because the way that the Amazon.com sight was NOT interacting completely.
This is the publisher's site:
http://www.usni.org/navalinstitutepress/index.aspAny combination of "Mariner's", "Mariner", "Pocket", and/or "Companion" in their search gets nothing.
Looked in all their reference sections, and can't find anything.
Looks like they don't publish it anymore.
I'll put this into my wife's hands (librarian and research is her forte) and see if she can find out more info.
As for Taurus's idea of creating your own reference, its a good idea. I was hoping there was something out there that covered 80%+ of stuff, then I could create a suppliment that would cover the remainder. But I can see this getting out of hand, very quickly... my flaw is scope creap ;-).
