Cocktail books, would (have) you buy one?

I’m trying to figure out who buys a cocktail/bartending book. I know that many sell each year but I can’t figure out who is buying them.

Does a cocktail book that has a large variety of soda-pop cocktails sound appealing to anyone?
I have one. And use it quite a bit.

Makes deciding what to make, with what youve got in the house, much easier.

Also, for people that typically stick to a certain type of hard alcohol (I pretty much always stick to vodka), it gives you a slew of difference drink recipes. It would take me a week of googling just to collect all of the recipes this book has for vodka drinks
