A little OT, but something your comments made
me think of:

What is the current, definitive book on COM?
(For the people who would like to some day
contribute to things like the above.  That is,
what is the best reference available for a 
"COM tools" implementor.)

I seem to recall hearing positive things about 
Don Box's "Essential COM" in the past, but I 
don't know if it has been surpassed by other 
books in the time since it was first published.

(If it matters - I'm currently not working with
.NET at all, but could be in the future.)
