Hmm, maybe I should mention this to the company I'm working with at the moment... It's one of the most famous atlas creators (at least, here, in the Netherlands). They've experience with creating atlases for over 130 years
(over 10 million copies sold so far, not bad!)
(the latest edition: the atlas of the Netherlands, has 560 pages and 2400 maps... it's a magnificent work, they have it on display in the hallway here...)
