Brilliant! Completely missed that. However, the $5 hardback unabridged collection of all three volumes cost 1/2 to 1/3 to price of ONE of the three volumes. I HATE the price gouging of publishers on ebooks. Not knowledgeable, but the production, personal costs,shipment and storage of physical books has to amount to at least 50% - 70% of the charged price and this reduction in cost should be reflected in price charged. eBooks often handle table, charts and maps poorly, but the fact that some epublishers can do it well suggest a lot don't bother to get it right - one publisher admits maps just don't work for them and make them available off their webpage. Rant over and thx for the advice.
