A phone call just now to the Floating Lotus USA number in the book itself got the "disconnected" recording, and there hasn't been an edition published past the 7th, so I suppose they've gone the way of a number of other small publishing houses. I'm sad to think this, but unless someone has some better news I suspect it's true.
The 6th edition shows an address at 2215-R #829 on Market Street in San Francisco and a PO box in Berkeley, both with the same phone and fax number. By the SF address I'm guessing it's also a PO box. Perhaps someone there would make note and check it out some time? It's more of a drive than I do very often from home here.
If you see an edition of The Men Of Thailand used anywhere - BUY IT. It's the one book I carry back and forth with me each trip, other than whatever novels I bring and a small Thai/English dictionary.
Admittedly the listings in it are now pretty dated, but the cultural information is still relevant.
The green one is the 6th edition, the "King's Yellow" one is the 7th. The spines of the books are the same color and they're a little over an inch thick.
