David Sparks has published his fourth Field Guide:

There are over 300 pages and nearly 1.5 hours of video screencasts and 200 screenshots as I walk you through. I’ve also included several audio interviews with friends including Serenity Caldwell, Rob Corddry, Merlin Mann, Fraser Speirs, Jeff Taekman, Aisha Tyler, David Wain, and Gabe Weatherhead, that provide even more perspective on the best ways to tackle email.

The book features a new craftsman-style design and is illustrated by Mike Rohde. In a lot of ways, this book feels like the culmination of everything I’ve learned along the way. I’m really proud of this book and I hope you enjoy reading it as much as I enjoyed creating it. It is available in the iBooks Store and PDF for $9.99.

I own every Field Guide, and David’s work has been a huge inspiraton for my Editorial book. I’m downloading the (1.1 GB) Email Field Guide as soon as I get my Internet back.
