World's Thickest Book

Intel should publish all of their documentation, including

http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-software-developer-manual-325462.html
and
http://www.intel.com/content/www/us/en/architecture-and-technology/64-ia-32-architectures-optimization-manual.html

in one book.

Nobody would use the x86 instruction set if it wasn't for PCs either. Intel spends time and money on 16-bit modes that address less than a thousandth of the RAM and ``conventional'' memory holes to mimic a 70's CPU in case someone wants to run DOS at 3 GHz, not to mention the instructions and segmentation mechanisms that nobody ever uses.
