A bound list of photogrammetric contracts is available for use onsite.

Four index maps covering the northern, southern, central, and western sections of the state function as a finding aid for the series. Individual map sheet numbers are indicated on the index maps, along with the approximate limits of coverage of each corresponding topographic map. An index number is assigned to groups of map sheets. At the bottom of each index map, there is a conversion list indicating the contract or project identification number (PIN) corresponding to each index number. That contract or PIN number is used to locate groups of maps, which are arranged therein by map sheet number.
