E-books need a common language

[Commentary] I never need to worry about whether I can read a book. As long as a book's a book, that is — printed on paper, in English. I know I can pick it up and read it no matter how long it sits on my shelf after I bought it. But as we move into the era of e-books, that assumption no longer holds. In certain cases, you can't read the electronic book you buy from one store on a device supported by a competing store. Similarly, you can't read e-books you borrow from your library if you don't have the right kind of device. And there's a chance you won't be able to read the e-books you buy today on the e-book reader you own several years from now. Does anyone in the books business realize how dumb this is? Seems not. Because just when the situation seemed to be getting better, it suddenly got worse.
