Seems odd............nowhere on the net could I find any reference to new editions of those books.  The 2004 and 2005 editions were published by Genealogical Pub Co., who lists them but says they are out of print.  I'd expect a blurb - "coming soon" - or some such thing.

I also found that those earlier editions are out of print nearly everywhere.  Ancestry.com has them from Richardson's site for $105 and $100, shipping costs for each $3.99.  Those would be new.  They also have them used at enormous prices from other sellers.

For my purposes, those earlier editions would serve.  They do contain my two royal lines - happily, I was able to verify that.  Would be a major investment..............
