This series spans the period 1972-1978 and documents the development of CARLA, Computerized Approach to Residential Land Analysis, by Beverly Willis, Eric Tiescholz, and Jochen Eigen. The system enabled architects to use computers to develop site plan design techniques more efficiently. It contains computer paper drive tapes of software program versions, a computer-punched paper drive of CARLA original film, flowcharts, videotapes, rough material for CARLA videotape, articles about computer-assisted analysis and mapping systems, computer manuals, and memos. Also included are Jochen Eigen's 1974 notes on interfacing CARLA with a computer mapping program.
