The clerk shall compile the master list by combining all the names from each source used and eliminating all duplicates or by selecting a sample of names from each source used by means of a random key number system. If a sample of names is selected from each source list, the same percentage of names must be selected from each list. One source list shall be designated a primary source. Names selected from the second source shall be compared with the entire list of names on the primary source. Duplicate names shall be removed from the second source sample and the remaining names shall be combined with the sample of names selected from the primary source to form the master list. If more than two source lists are used, this process shall be repeated, using the previously combined list for comparison with the third source list, and so on.
