Thanks for posting that link EttaMae. I was thinking about this thread and I was going to recommend the Red Cross First Aid course, but the review you found was very interesting. Still, I'd think that any care would be better than no care so it might be worthwhile to have as a reference book.
I have the Merck Veterinary Manual, but I definitely wouldn't call that a quick reference book.

There are some others, but this one was mid range price and looked fairly comprehensive.
