Hi Bellybones,
Don't worry about the multiple postings. I think we've all done it at one time or another.
There's a link to information about the Modern Antiquarian book at the top of all the pages on this site (in yellow pinky red background). That takes you to this web page...
http://www.themodernantiquarian.com/the_book/
Despite the claim that you can buy a copy of the book from Head Heritage, I must admit I couldn't find any trace of it.
Unless anyone else has any bright ideas I'd suggest you look on Amazon or failing that Ebay.
Sorry. Not very helpful.
