Maybe I should have written, as an OPTION sell segments of the main book for people with special interests who would like to take one smaller version aong on trips.

I agree with you, I'll carry the book or a whole encyclopedia if necessary. A single book is better.

Then there's the blacklight, magnifying glass and pretend stone face when someone offers me an old chip for $10 that books at $50. Don't play poker with me, I have more tells than a Tarot card reader.
