Bruce Crawford, formerly of WDG, WDW, and WDFW has written Preserve, Protect, and Perpetuate. A History of Washington State Fish and Wildlife Management. The book includes sections on the history of WDF by Duane and Lloyd Phinney.

I have only skimmed it but find it fascinating. The book started with the Tribes pre European arrivals includes the treaties and moves on thorough all the changes in management and organization. A lot of the book is about the people and how they did their jobs.

The book is self-published, so its not on Amazon. If there is interest can post the details.
