If you are buying from The Americas, you should address to the NY Springer site:

Buy Volume 1 from The Americas

Buy Volume 2 from The Americas



If you are buying from anywhere else in the world, you should address to Springer International

Buy Volume 1 from Africa, Asia, Australia or Europe

Buy Volume 2 from Africa, Asia, Australia or Europe



Please, note that, although the two volumes are sold separately,
the volumes have really been conceived as one single book and
we recommend they are bought together.

You will get a reduced price if you purchase the two-volume set.
The reduce price is 150 US$ if you are buying from
The Americas and 199 euros if you are buying from anywhere
else in the world.
