These letterbooks include cover letters to accompany election notices and pay vouchers. Most of the correspondence relates to registration instructions and determinations, appointments of election officers, resignations, the canvas of returns, polygamy convictions, and the Women's Christian Industrial Home. Many of the letters copied in these letterbooks are illegible. No letterbook is available for the period from mid-January 1885 until August 1888. Each letterbook has an index to addressees at the beginning.
Entries are alphabetical by the first letter of the surname.
The last two indices are incomplete. The Utah Commission was disbanded when Utah became a state in 1896. At that time, three Commission letterbooks and two from the Women's Christian Industrial Home Association were turned over to the Secretary of State along with the other records of the Utah Commission. The archives obtained the Utah Commission's records from the Secretary of State's office in 1957. Microfilming was done in 1960.
