| Sumario: | According to Martha E. Williams, information scientist at the University of Illinois at Urbana-Champaign, records on publicly available data bases have grown from 52 million in 1976 to 1.68 billion in 1985. A researcher at a computer terminal linked by phone to a data base can type in a key word and receive all records that contain the key word. About 36 percent of data bases contain numeric information; another 36 percent contain bibliographic information. Others provide access to articles, the texts of legal cases, and other materials. More than half the data bases are located in the United States. Williams compiled and wrote Computer-Readable Data-Bases: A Directory and Data Source Book. |
