Nothing fancy, and just about any notebook would suit the purpose of keeping research and thoughts in a single place. In this instance I’m using a Moleskine Cashier’s Journal from a six pack picked up a Costco a few weeks back. It’s probably too big for the purpose but I can use it to contain additional research during and following WordCamp Riverside 2017.
