"A massive list of mostly critical references cites the most important works the world over." (CHOICE, November 2009)"An excellent in‑depth overview on one of the most revolutionary topics in the earth sciences. … Not only clear and comprehensive, but also pleasant to read. It is a highly recommended must‑have on the bookshelves of earth scientists for some time to come." (Geologos, December 2009)
"Global Tectonics will find its place in all well equipped libraries and a personal copy will be of use for any geoscientist who needs a comprehensive overview." (Surveys in Geophysics, September 2009)
"This textbook provides a comprehensive overview of the field of global tectonics. Because the field has changed significantly since the last edition was published, the majority of text and figures in the third edition are new." (Book News, September 2009)
