Note: In the effort to make the book searchable, we used a process called Optical Character Recognition (OCR). Occasionally there are some OCR errors in the book (mainly formatting, i.e. bold or italic instead of normal), but they are relatively rare and will be corrected in a future version.

Stephan Weiss maintains a list of comments and corrections of Martin's book.
