Nothing much to add to that. Well written, good illustrations, all's good, but too superficial and cursory. Unfortunately, short of reading gnu source code, it's the only info source on the topic, so one has to be grateful for what one can get, I guess. For what it is, the book is OK.

I learned a lot about object files, loading and linking from reading this book.

This is one of the excellent book, that gives enormous information to know how object files are created and how linker in various OS works.
