I initally wanted to know if this was the British or American version but then was able to answer my own question by looking at the name of the publisher. But what makes this different than the normal set. Is it bound differently?
What I want to know is this: are they actually sewn, or just glued? I'm in the USA an I really want to get the British edition, but all the "hardcover" HP books we have are just glued -- it's like a paperback book glued into hard covers, and falls apart sooner rather than later. If this really is sewn, I'll be happy to buy it and pay the shipping to get it here (I live in Seattle).
