Yes....I assume that you have read that the other volumes are coming, but will be a bit delayed. One of the best series of photographic books that one can buy. Moreover, considering the unsurpassed quality of the reproductions, the price is amazingly fair.
The printer of the books, Salto, is instituting a new technology, hence one reason for the delay. The other reason is that the one portfolio that was not scanned originally, was just scanned. I spoke with Salto today and we are now working on a date for printing. Early fall to late November is my best guess at this time.
