Most records held by the Utah State Archives are not indexed. Some creating agencies may have indexed records series, but frequently these are found as an index at the beginning or end of an individual volume, or as a separate records series. Such indexes are then available in paper or on microfilm.
A few series are indexed electronically. These indexes may only index part of a series--particularly if there is already an index available in paper or microfilm to the remainder of the series. Occasional electronic indexes index an entire series.
