The Pottermore Store is now open, selling English-language copies of the Harry Potter books. Other languages will be coming soon.
The good news: the books are pretty reasonably priced ($7.99 for the first one).
The bad news: if you live in the U.S., you can’t buy the original version but are forced to buy the U.S. language version.
For a lot of people, maybe most, that won’t matter, but I read them originally in British English, the original, and I don’t want them in U.S. English. So my excitement about having them available, following many months of anticipation, was quickly turned to major disappointment. Since JKR owns the digital rights to her books, I don’t understand why she would keep people from buying them in the original just because they live in the U.S. It’s not like where different companies in different countries have the rights to them. Anyway, after this long wait, sadly I will not be buying the books in e-book format.
It’s too bad that the British English editions are unavailable to people in the US. Since I have hardcover editions of the books, this isn’t really an issue for me either, but I always found the British English editions preferable (partly because the books themselves are set in the UK). I agree that that’s a disappointing development.
