I'm glad these are available, and spiral binding makes them a lot easier to read. I have some hard bound ones and they're extremely stiff.
$10 shipping per books seems awfully high. Too bad they won't combine shipping. In any event, these are excellent resources and every engraver should at least have Art Monograms & Lettering. BTW, there's a free version on Google Books but the resolution isn't that great. Sufficient but not great. The printed version is far better.
You can download it to a jump drive and take it to Office Depot or similar place and they will print and bind it for you for a nominal fee. Just be sure to include the page that says it is royalty free. Mine is plastic spiral bound with a acetate cover and cost IIRC around $10.
