Just treated myself to a new book Glass Art Reflections Of The Centuries. I havent had a chance to have a proper look as yet, but after a quick flick through would say its well worth a look, its crammed full of stunning lavish photo's i would say about 90% colour. 384 pages, From very early pieces, pre roman through to early 1990's. There is a lot of high end pieces but there are some more affordable for those of us that havent made our millions just yet
. There is no price guides in this book but lots of information.
He also wrote Czech Glass 1945-1980: Design in the Age of Diversity which i mentioned previously
Ive not seen one one ebay but they are selling on amazon
all the best
