What is the Blue Book of Idaho?
The Blue Book of Idaho is published biennially in odd-numbered years under the direction of the Secretary of State. It contains constitutional, historical and statistical information about the state of Idaho. It also details the structure of Idaho’s government and includes biographies of elected officials. The book is distributed free to all schools and libraries in the state upon request.
The Blue Book received its name not from the color of its cover but rather by definition of content. Bartlett’s Dictionary of Americanisms defines the term Blue Book as “a printed book containing the names of all persons holding office under the Government of the United States. It answers the Red Book of England.” Individual states have taken this concept and expanded it to include a wealth of information about state officials, resources, and historical profiles.
Latest Edition
Twenty-Eighth Edition: 2025-2026
This edition, we re-imagined the blue book as an exciting visual almanac of Idaho’s history and culture, while retaining its primary function as a directory of elected officials.
The goal was to create a book that can be proudly displayed and tells Idaho’s story in an engaging new way. We worked closely with the Idaho State Historical Society to create new articles and to display a small selection of the treasure trove of historical imagery that chronicles our beautiful state.Â
We sincerely hope you enjoy it.
