Is the handbook more or less in-depth than Intel's Programmer's Reference
Manual (for 386 or 486)?  I have found numerous errors and omissions in the
Prog. Ref. Manuals.  For example, almost none of the pseudo-code provided
in the detailed instruction descriptions is error-free, and both books
never mention what happens to INT/IRET in virtual 8086 mode when IOPL is 3!
Also, there were only a couple of programming examples (for Code Builder, I
think).

What I'm looking for is a book that leaves nothing to the imagination,
which I would have expected from official documentation.  Either that or
some decent programming examples for the various modes including virtual
8086 mode!
