The Blue Book of Idaho

The Blue Book of Idaho

Latest Edition

Twenty-Eighth Edition (2025-2026)

The Idaho Blue Book is published every other year under the direction of the Secretary of State. Over the last several editions, many sections of the book have remained largely unchanged. This edition, we decided to re-imagine the book as an exciting visual almanac of Idaho’s history and culture, while retaining its primary function as a directory of elected officials.

The Idaho Secretary of State’s office worked closely with the Idaho State Historical Society to create new articles and display a small selection of the treasure trove of historical imagery that chronicles our beautiful state.

Our goal was to create a book that could be proudly displayed with content that is engaging and tells the story of this great state.

We sincerely hope you enjoy it. 

A limited quantity of printed copies are available for $20.00 each, or you can download the digital edition for free.

System Upgrade In Progress

Campaign Finance, Lobbyist Reporting, and Online Voter Tools are expected to be offline from April 9th at 5:00 p.m. MDT, through April 12th at 8:00 a.m. MDT to complete a system upgrade.

Per Idaho Code 67-6607, campaign finance is reported monthly during a campaign’s election year. The deadline for the March report falls on Saturday, April 10th. Due to the interruption caused by this upgrade, political treasurers will be allowed to file the March report until 11:59 p.m. MDT on Monday, April 12th.

While we do our best to ensure compliance with all deadlines in statute, the timing of this release is critical to ensure minimal (or no) impact to the May election cycle. We are sorry for any inconvenience this may cause.
