While looking for the titles that have been suggested to me I found this source that looks very good for ww2 books. http://www.sonic.net/~bstone/site_index.shtml I hope this might help someone out.
Stone & Stone are highly recommended in the USA, maxwell and you should find many of your 'wants' there. Also, for out-of-print titles, don't be afraid to check out 'bookfinder' or 'abebooks' on the 'net. Some of 'our' type of books can be found there for surprisingly low prices ; I've filled in many gaps in my collection this way with - so far - 100% excellent service from the various dealers.
Maxwell, I agree with Martin but you may also want to work slowly through the books and publications forum and check the posts as there are many other book dealers on-line and non. www.tollehausbooks.com www.angelraybooks.com seems the site has been down for weeks as there is severe illness in the familie. www.germanbooks.com there are many others of course ^E^
I've been doing just that, Started with General Discussion, and I'am working my way through them. If I ask a question that has already been asked please be easy on me ok
