Intro copy...Artists with technical requests were matched with engineers and scientists who produced information and assistance or participated in longer collaborations. The system for providing information and matchings was expanded several times after its inception, including a proposal to develop a computer-based directory of artists, scientists, engineers, researchers and other professionals. One of the first innovations in the system was to use edge-notch cards to hold information on the technical specialties of over 1,000 engineers. A computer database of engineers and scientists was compiled which artists could refer to as they needed specific expertise.
