I stumbled across these notebooks in a local gift shop and think they are ideal for keeping exposure records and general note keeping.

Tall, but slim enough to fit in a front shirt pocket and with a good hinge that flips back out of the way. It even has a pocket on the back inside cover to hold a few business cards.
Obstensibly, they are for news reporters, but are just the form factor I was looking for.
I think they are great!

Front Page Reporter's Notebook
Our reporter's notebook measures 3.75" x 8" with a top spiral binding, college-ruled paper, and a back pocket for stashing receipts or shreds of evidence.
