Here, in India, we get "Indian Edition" or "South Asian Edition" or "Asian Edition" of American textbooks. These textbooks are usually adapted for these regions by professors of Indian universities.
These editions have altered arrangement of chapters and even topics within the chapters. Sometimes some extra topics/chapters are included, while some other times some topics/chapters are excluded.
This is something I usually dislike, as I feel that titles should be accessible *the way they are* from anywhere in the world.
But, today I was reading the Indian edition of this book "An Introduction to Mechanics" by Daniel Kleppner and Robert Kolenkow, and I was actually impressed seeing the order of arrangement of the topics, which was better than the original American edition (that I pirated).
In the US, the Indian editions are often sold cheaply on the used market, especially online. As I understand it, the rearrangement of chapters and problems is to allow the publisher to charge higher rates in one jurisdiction than in the other by reducing this arbitrage. A student who buys the Indian edition still needs access to the American edition in order to figure out which chapter or problem corresponds to the one assigned by the professor.
