Which looks quite good, but isn't exactly cheap! I downloaded the PPro reference manuals as PDFs from Intel, and although they seem pretty well written, they're only really useful as a technical reference.
In fact you should find out almost everything about ia32 by studying Intel's "Intel Architecture Software Developer's Manual" vol. 1 through 3. The remaining information is scattered across various documents and hard to find even though many of them are available from Intel on-line.
Beware, also, some statements in Intel docs are incorrect. It's still unknown whether these errors are intentional or not (see http://www.x86.org/ and http://www.sandpile.org/ for a discussion) but you'd better verify everything with a real chip (I don't mean "reserved" areas here; these are to be documented features).
