I'm working with county-level voter registration records in California, 1866-1872. Before an election, the County Clerk had at least 10 copies of the County's "Great Register" printed. These were distributed to the County's election officials. The early versions of these printed copies were booklets with a title cover without publication information. Later they were submitted as print jobs to local printers, who added their names, publication dates, and places. Sometimes the cover will carry the statement, "Published by Authority."
