I know that if I were going to start playing bridge again, I would
read Watson's "Outline of Contract Bridge" first

because you are aware of its existence. Most newcomers to the game of
bridge won't recognize the name Louis Watson any more than they will
the name Kenneth Harkness, and, preferring new books to old as you
note so many people do, my guess is that they will buy the books their
friends or teachers recommend, or they will browse at the local
Borders or B&N and find something there rather than take a chance on
publishers' blurbs on Amazon.

The reviews that will come out in Bridge Bulletin and The Bridge World
and perhaps other magazines (you have sent out or will be sending out
review copies of your titles of course) may help, though a survey
commissioned by ACBL a couple of years back found that the vast
majority of bridge players in the US had never heard of ACBL, so they
would not see the Bulletin review-to-be anyway. Otherwise I'm just
not clear on how your intended customers will encounter your
products. The good news is that the market doesn't much care what I
or any other individual consumer thinks. Only time will tell.
