From the Lawrence Daily Journal-World for Aug. 20, 1972:
Douglas County had made the move to computers this summer. Up until recently, only the largest counties had used computers to calculate their property tax assessments and perform internal administrative duties, but in the last few years a few moderate-size counties had modernized their procedures as well. If all went according to schedule, Douglas County citizens would first see the change in November 1973, when the first computer-generated property tax statements were expected to be mailed out. Computer programmer James Tate was currently recording on data-processing cards information about all of the estimated 25,000 pieces of property. Working with hand-kept records in the county assessor's office, the county's one keypunch operator and one verifier had so far almost completed the listings in all of the townships and were about to start on the county's four major cities, a task that was expected to take them into February. The county had purchased its own key-punch and verifying machines, but not a computer -- they were renting computer time from Lawrence High School.
