Main Question or Discussion Point

Dear all,
what are the differences between Caroll´s GR published book and the PDF text?
Thanks,

One big difference is that Chapter 9 from the published book, Quantum Field Theory in Curved Spacetime, is not included at all in the pdf version. This chapter is a nice introduction to the topic.

From Sean Carroll's webpages,

"About 50% of the book is completely new; I've also polished and improved many of the explanations, and made the organization more flexible and user-friendly."
