If no one on your team is keeping a book I would like to suggest that you volunteer to "step up" and keep an electronic book for the team. I would recommend using iScore. It is cheap and others can follow along online if they are not able to be there. It will also give you the ability to produce stats for everyone. The coaches may even appreciate it if you are a reasonable scorekeeper.
I wish I could use something electronic. I used to enjoy keeping the score, and seeing the details of the game, when I went to MLB games. Unfortunately, because of a pain disability I cannot hold most small things like pencils, iPhones, even iPads are painful for me to hold.
A parent does keep the book for the coaches. I guess I should just ask if I could make copies of it.
