Anyone interested in learning more about how tax avoidance and havens work as well as large company 'best-practices' might be interested in reading Treasure Islands by Nicholas Shaxson.
For anyone who'd like to read more about transfer pricing, here are the OECD guidelines that tax lawyers/accoutants use: http://people.f3.htw-berlin.de/Professoren/vonWuntsch/downlo.... You'll see these cited in every international transfer pricing case.
I think it's only language (color vs colour) and the book cover. I can imagine the UK version of the book cover would not have gone down well with the US audience (and vice versa).
